Title: Some notes not playing
Post by: r010159 on June 14, 2021, 11:00:02 AM

When turned on, I play a series of notes. Some notes may not play, but with repeated playing, then other notes may not play. If I play staccato, I have no problems. However, when I change a parameter or two, there is no problem.I can then play legato.

Any ideas? Do I need to update the firmware? This is a new unit. I am at firmware version 1.1.0.

Thanks!

There now is oscillator instability. I think it may be caused by the high temperature in the room which os above 90. I do not know.

Maybe there are multiple causes, one for the instability, and for the original problem, sonething else.

Not good.

Have you tried to run calibration? It should be in the globals menu somewhere.

I recently had similar problems to this. I needed to take two actions
1) I had a midi feedback-loop in my setup and needed to fix it
2) I needed to re-run calibration

In addition to running calibration, do you have any USB or MIDI cables connected? If so, do you still have this after removing the cables?

Thank you for your reply!

I have removed the MIDI cables, and recalibrated the filters and oscillators. So far this seemed to have worked

FWIW by far, this has been the largest purchase of mine in a synthesizer. I cannot afford to have a malfunctioning  one. Thanks for your help.

I am having the same problem again. I think it’s a temperature issue. The temperature inside of my home is 90 to 95°. Otherwise, I do not know what is causing it.
