"Steppy" sounding MIDI LFO's using thinning

#1

I'm using the midi/out/ccthin object to output LFO k-rate to my OP1 synth as an auxiliary LFO. The only issue is that it is fairly "steppy" sounding, even using a sine wave. I'm guessing this is maybe to do with the thinning process?

If so, it would be easy to use the midi/out/cc object, however this requires a trig input, and I can't work out how to allow it to freely stream the k-rate without re-triggering my keyboard. Using a toggle didn't work either. Is there a way to completely remove the trig part of the object so it just constantly sends un-thinned MIDI cc without a trigger? I tried altering the code within Text Editor but it did not compile - probably because I'm a complete numpty when it comes to code...! Will removing the thinning possibly cause MIDI message overflow?

Have you tried triggering it with a very fast square LFO ? That's how I seem to do it when I find the thin version too steppy.
It needs to have some kind of information limiter because the midi standard isn't very good at transmitting big amounts of information. I think anyway, I wouldn't mind someone telling me I'm wrong :slight_smile:

If you send too much MIDI data at the same time, you'll overflow the MIDI data buffer, and Bad Things might happen.

Thanks @mytas - tried that one and it's a bit better, but still a bit steppy. I'm wondering if it's the actual OP1 that just doesn't process the MIDI smoothly. Going to have to pull out my broken Nord and see if I can eliminate that as a problem

You can try the drj/midi/cc_thin_var object which provides MIDI CC transmission at a user selectable rate of 1 to 1000 CCs per second. Hopefully this will let you reduce the stepping to acceptable levels.
