Neutron tuning stability tests

Does the behringer Neutron have a serious design flaw? I test the tuning stability of two neutrons and compare that to an ms20 mini. I let all synths warm up for a few hours before conducting this test.

First neutron had pitch fluctuations of 1.5hz

Second neutron had pitch fluctuations of 1.1hz

Korg MS20 mini had pitch fluctuations of 0.3hz

All instruments were tested using a single saw oscillator with the filter open and no resonance. Tuning was measured with the n-Track Tuner pro app on an iPad using the Roland goMixer as an interface.

I wouldn’t consider this a scientific test but it confirms what my ears were telling me, that there is a serious issue with the Osc stability on the behringer Neutron.

If you would like to see any other specific type of configuration tested let me know in the comments.
