**Update: Investigated further. It seems that aftertouch and ENV 1 do not modulate with full 12 voice polyphony when using the ST49. They modulate on one key press but not the second press and so on. So if you built a 12-voice patch with AT modulating anything on the board, it will only modulate that destination on every other key press. Basically unusable.
Original post:
Anyone else have the issue with LFO 2 in 12-voice mode? It’s like it’s only 6 voice polyphonic vs 12 as when I route it to cutoff or pitch and try to trigger it with aftertouch, it only triggers on ever other note and with a maximum of 6 running simultaneously.
To test this, just put the synth in a init patch into 12 voice mode. In the perf control section, turn the toggle to AT + Trig. Turn up the pitch or cutoff or both to max. Then set your LFO rate to something in the middle and trigger the LFO by pressing one key and adding aftertouch. Then let go, and press the same key again and add pressure for aftertouch. What happens on mine is that the second press, third and fourth alternates between triggering the LFO 2 on and off.
Ok, this is not an issue just with LFO 2. It’s an issue with using ENV 1 as a source and when using After touch to modulation LFO 1 rate for example. I’m using the ST49 keyboard. I’m only able to get modulation with AT on LFO 1 rate, as an example, on every other key press.
Really annoying. It ruins 12-voice patches where I want to take advantage of polyphonic aftertouch modulating either of the LFO (1 or 2) rates.
I contacted them a few months ago about this and they said it wasn’t a bug, I hope they don’t mind me sharing what they said:
What you’ve described is normal behaviour. This is due to the fact that there’s only a limited subset of non-binaural modulation options. While both LFOs can directly modulate certain modulation destinations per voice in non-binaural mode (for example pitch or the filter cutoff frequency), the individual LFO parameters cannot be modulated with each non-binaural voice. This is because parameters such as LFO 1 and LFO 2 RATE don’t feature left and right channels for modulations. It is therefore normal that their rate is only modulated every other voice in non-binaural mode.
Isn’t it that you only can’t modulate the rate of lfo with at? You can still use at to apply the lfo to something if I’ve got it right. Still a bummer, I was pretty disappointed
In my case I was trying to modulate the rate of lfo with an envelope
I mostly use binaural mode so it doesn’t affect much, but they really should fix this. I guess they implemented it this way because it was easy, and they didn’t have to rewrite some code. The given explanation is just an excuse for lazyness and other priorities.
A simple short-term fix would be to allow Global Menu switching between polyAT and regular monophonic aftertouch.
