Title: LFO trigger modes
Post by: pix on August 26, 2017, 06:48:51 PM
I'm having a problem with LFO trigs. On some patches the LFOs stop triggering no matter what the settings are.

It seems to occur when there's multiple destinations assigned in the matrix. However if I clear the matrix after this happens the LFOs continue to not trigger.

Has this happened to any of you?
Title: Lfo trigger modes

Hello pix,

it's not a bug, it's a feature.

The engine supports several different sync/trigger modes for the Arp/Lfo. You can select them in SETUP. The advantage of having different trigger modes is that you can sync the Arp/Gate/Step/Lfos with each other. The soft trigger mode is an innovative mode, which makes it more easy to play the arpeggiator or trancegates in life performances. They don't get 'out-of-the beat'.

Arp/Lfo hard trig:
If TRIG is on every voice will retrigger. The LFOs behave like polyphonic LFOs.
If TRIG is off the LFOs will retrigger with PHASE as soon as the first key is pressed.

Arp/Lfo free:
A free running and monophonic LFO

Arp soft Lfo hard:
Soft triggering Arp (see below) + hard triggering Arp

Arp/Lfo soft trig (the default mode when you init a patch):
If TRIG is on every voice will retrigger. The LFOs behave like polyphonic LFOs.
If TRIG is off the LFO will only retrigger when no key has been pressed during the last second. Othewise they will behave like freerunning LFOs.

Arp/Lfo classic trig:
If TRIG is on every voice will retrigger. The LFOs behave like polyphonic LFOs.
If TRIG is off you get a free running LFO

OK, found the issue. The problem is that I was using monophonic mode. When I change to polyphonic 1 the LFOs restart just as you described.

What is the exact difference between monophonic and polyphonic 1 modes?

The differenrce is the way how new voices are triggered:
 
On monophonic mode one voice is playing. This is what monophonic analog synths do. Here the oscs usually do not reset when a second key is pressed.  It's good for lead sounds, analog sounds or if you use glide.

On polyphonic 1 mode the old voice is quickly faded out when a second key is pressed. It is usefull if you do wish digital precison. The osc and lfos can retrigger hard without producing unwanted clicks. It is useful for punchy bass or basedrum sounds which retrigger the oscs.

got it, thanks! I think it'd be nice to have the osc phase reset separately from the LFO trig reset.

Right now in monophonic mode the LFOs do not reset wit the new key press.
