Part four of a getting started guide for the Erica Synths LXR-02 drum machine. This is with a beta version of firmware 1.2. This tutorial covers the fundamentals of patterns with a focus on the pattern generator. The generator is a Euclidean pattern generator but is so fast and versatile it's useful as a starter in just about any situation. The tutorial also looks at pattern and track lengths and clearing tracks.
This was also going to cover song mode but (and please test this for yourself) I believe there's a bug in song mode where the song plays backs patterns one-higher than the saved pattern number. So if your song says play back patterns 1, 2 and 3 it will actually play patterns 2, 3 and 4. As soon as this is fixed I'll do a video on song mode!
Note also in the pattern generator page that "mrp" is a morph control and will also be covered in a separate video.

The Fairfield Circuitry Hors d'Oeuvre pedal is a feedback device. It will act as a sort of distortion by itself but where it shines is with another pedal in its send and return loop. Here I have an MXR Phase-95 followed by a Vahlbruch delay in the loop. The DB-01 is initially running through the Boss GEB-7 EQ pedal, then into the Hors d'Oeuvre.
There are no other effects or processing other than a limiter on the output and a little volume balancing to avoid anyone having to ride the volume knob. The Hors d'Oeuvre is quite sensitive and small adjustments in feedback or phase position can make a big difference to the sound.
I teamed the Hors d'Oeuvre with a couple of other pedals but it definitely seemed to work better with analog devices. For example, a cheap digital reverb I tried gave nothing but painful squeals.

Part two of a getting started guide for the Erica Synths LXR-02 drum machine. This is with firmware version 1.1. This tutorial covers initializing a new project, adjusting basic configuration settings, using an external MIDI controller, and a run through of the voice editing parameters. Here we look at just the main drum synth voice that is used in the first three voices. Toward the end we create some basic drum sounds from scratch including some clean kicks, a few awful FM things and various flavors of snare. The remaining three voices: snare, clap and hats (and some better FM) - will be in the next tutorial.

** A couple of minor points: At 5:00 minutes I delete some content on Pattern 1. On very rare ocassions when initializing a project I get random (but coherant!) content on Pattern 1. Of course it happened while videoing. Also, a few people would have seen an earlier "tutorial 2". This was based on the operation of the LXR-02 with an earlier SD card image which didn't allow for simple project initialization. The improved software made that video largely irrelevant so I deleted it. That's the danger with early version tutorials!

The Erica Synths DB-01 sends and receives CV and includes a handy attenuator, so a little experimentation with CV can really extend the sound design possibilities. Here both DB-01s and a pod of Euro clocks and modulators (two Erica Synths Drum Modulators) are synced together. One DB-01 is the master feeding pitch CV into a mult and then into the second DB-01. Both units are getting filter CV inputs from the Drum Modulators. The main machine is sometimes going through a Microtubes B3K for extra overdrive goodness, and the second DB-01 get washy with an Earthquaker Devices Afterneath V3 - which also accepts CV. Hopefully this little demo gives you some ideas. A little CV goes a long way.

I bought the Erica Synths Zen Delay intending to pair it up permanently on drum duty. On a whim I hooked it up to my OB-6 and I think that's where it going to live from now on. There's something about the Zen that seems to pair with the OB-6 so well, some added soft richness and a dreamy reverb-like quality.
This track is a single take recorded as a MIDI track into Reaper. I then played back the melody while tweaking the filter and resonance as you see here. There's absolutely no other effects, automation, sounds or tweaking. Just an OB-6 and a Zen.

There's plenty of videos which show Earthquaker Devices' Afterneath V3 doing all the usual reverb things, so here I thought I'd just show what happens when you apply CV. The expression jack accept 1v/Oct CV, although it doesn't track pitch. Because of that I mostly ignore the Major, Minor, Pentatonic scale modes because they don't really work anyway in terms of tracking pitch. Despite that there's lots of interesting weirdness to explore.
Here I'm running a DB-01 through the pedal. the DB-01 CV out is being mixed with the CV from a synced LFO. I experiment with different LFO shapes, rates, and blends of the LFO and DB-01 pitch CV.
In my first edit of this video I chopped everything up into highlights, but I abandoned all that and went with the unedited noodling instead. I think it's more interesting to see the process of getting from one effect to the next even if that means a few interludes of mush. Hope you find it useful.
ps: This is not a sponsored video, I bought it at full price with my own money.

Do you find that certain combinations of gear suddenly become "more than the sum of its parts"? The OB-6 has become a huge magnet for my time these past few weeks since I've teamed it up with the Erica Synths Zen delay. This piece is a little similar to the "OB-Zen Nocturne", but instead of manual twiddling of the filter and resonance knobs they're now hooked up to the little MIDI fader box on the left. The far left slider is filter amount; the middle one is resonance. The other fader (which I didn't use here) was assigned to filter EG amount. The benefit of the fader box is the ability to tweak both parameters together while also playing with one hand.
Clearly I'm not playing each note of the arpeggiated chords, just triggering chords. That's done using the plugin "Cthulhu" by Xfer with a range of chords I assigned per note. The piece begins with G Minor 9th, then a G# maj9. After recording I added a touch of EQ and some compression since the big octave range and varying filter and resonance settings gave it some pretty wide dynamics.

Some random noodlings with the Avalanche Run V2. Bought this because of the knob-per-function controls. It's certainly very easy to operate and gives a big thick sound. The Tone control works beautifully on the delay and the reverb is rich. On the other hand a little more stereo separation would be nice and you do need to be careful on the levels as it will clip fairly easily with a loud pop and crackle. I tried hooking up the DB-01 CV out to the expression in but the results were disappointing. Likewise using an expression pedal didn't seem worth the effort when using it on the desktop since all the controls are exposed anyway. Still, what you're paying for here is a beautifully thick stereo sound and superfast and simple tweaking. What a relief not to worry about menus and secondary functions!

The Erica Synths DB-01 plus a single Eurorack LFO module (the Erica Synths Drum Modulator) can achieve generative dark ambient. Seems unlikely but is really very straightforward. In this example it even sounds a bit like a thunderstorm. An Eventide Blackhole provides the obligatory big dark reverb and there's also some limiting in the DAW from a Fabfilter Pro-L.

Audio here is 100% generative and is an untouched, unedited slice (starting at 53-minutes in) from the 9-hour MP3 download version. Tones are from a relatively simple Eurorack patch with Interstellar Radio's (IR) two oscillator outputs going into an Erica Synths Black Dual VCF left and right. IR left-CV is being fed by a separate random source, right-CV from the error output, while the VCF is also getting smooth random CV into both sides as well as into resonance. A little noise is separately being fed through Anglegrinder. The whole thing then goes through a little Valhalla delay and Fabfilter Pro-R reverb. Pro-Q3 pulls everything into mono below about 200Hz which helps tie it all together. The stereo separation of the two oscillators is especially clear with headphones.

Video begins with a clip from Golem (1920), with the remainder being from the 1916 Danish sci-fi short Verdens Undergang (The End of the World).

Patrons can download a 9-hour long 256K MP3 of the audio. It is a full 9-hour one-pass stream and has no loops. Makes rather good sleep audio!

If you ever played around with shortwave radio noise as a kid then this is your grownup noise evolution. Schlappi Engineering's "Interstellar Radio" module wants you to endlessly twiddle and wiggle and enjoy the lack of melody and float away in the squeals and static. With all the controls normalled to produce sound on their own this is also a great module for a small system or someone starting out in Eurorack (assuming you like noise).
Here I go through the basic controls, how to understand a little of what you're doing, and then indulge in lots of wiggling.

Can two Erica Synths DB-01 Bassline machines achieve Subharmonicon-style ambience? They are wildly different in design and capabilities but the DB-01s can do a surprisingly good impression of "meandering ambience". Here I run through the entire setup and tweaks with less talking as the video goes on. What I did find is that the wonderful Polivoks filter won't be denied and the machines seemed to naturally gravitate to grit and filth and finally ended up in dark ambient territory. For contrast listen at 4:35 and then jump to 20:20. Both machines are running through the same Fabfilter Pro-R reverb setting at a 25% mix.
PS: The focus becomes steadily softer through the video. Why? Who knows, but it's the last time that camera will fail me. Next time, a new camera.

Was setting up to attempt some gentle ambient bleeps on the DB-01 (yes, really!) when the B3K bass overdrive begged a moments attention. Before I could say "this wasn't the plan" the second machine was on, both were in keyboard mode, and the droning began. Anyone with non-programmable synths knows you have to capture the moment before a single twiddle vaporizes the sound forever, so here it is. Effects on the right-side synth are the B3K into the Vahlbruch SpaceTime delay. The left unit goes from the GEB-7 bass EQ into the DD-8 delay. Both then get a touch of Fabfilter Pro-R reverb (on the "Huge Synth Space" preset). No other effects. Drums come from a single pattern on the Norand Mono. Good headphones or speakers will reward with some very heavy bass.

A look at some of the obvious and not so obvious things you can do to get a variety of sounds. Especially important is the use of LFO phase shifting, something which was introduced in firmware 1.07.

What do you get when you add extra bass overdrive onto the already aggressive DB-01 bassline synth? Beautiful growling! This no-talking demo attempts to find some of the sweet spots and shows the effect of the mid boost and "grunt" boost. No other effects or processing are used other than the pedal.
I've also made a small sample pack of 16 one-shot wavs (tuned to C) and loops for Patreon supporters to freely use in productions.
This pedal was bought at full price by me and was not a review copy or freebie. If you're interested in getting one be aware that at high blend and tone you do get some noise and hiss.

Sergei Korolev was the driving force behind most of the early Soviet successes in space from Sputnik to Vostok-1. Although his last rocket, the massive N-1 failed, Korolev's influence lives on even today in the incredible Soyuz launcher. "Korolev's Last Rocket" (Последняя ракета Королев) is a tribute to Korolev, Gagarin's Vostok-1 mission and the N-1. Release date is to mark the 60th anniversary of human spaceflight: Gagarin's Vostok-1 mission of April 12th 1961. (April 12th is also the annual International Day of Human Space Flight).
Russian ground control audio at the start of the clip is from a modern Soyuz launch; the audio at the end is radio chatter between Korolev and Gagarin. The track was written at DubDub studios and mastered by Scott Craggs at Old Colony Mastering.

How can you make a 16-step pattern into a 32 or even a 128-step pattern without creating multiple bars? Just use the "cycling steps" feature. There are various "cycling step" options available such as 1/2 2/3 3/4 or 7/8. By adding just a few you can make a very simple 16-step pattern into a much more complex and varied "Super-16".

I wasn't going to talk at all but there's a couple of quirks in the D-Seed that I had to mention: Not being able to turn down ping-pong mode; and the frequent need to tap tempo. But it's cheap, stereo and sounds good. After the first couple of minutes I shut-up and noodle at length with all the modes. As usual no other effects or processing except the synth and the pedal. Meanwhile my credit card is nagging me about buying delay pedals - especially since none of them seem exactly right.

Some initial noodling with my newly purchased NUX Duotime. Nice solid metal case with stereo in and out. The feedback knobs are limited so they can't get into speaker-busting oscillation - so you get all the anxiety of runaway repeats with none of the damage.

Here I just faff about on the DB-01 while going through each mode. Note at the end the Verb setting has a shimmer you can dial in. No other effects, EQ or limiting used.
