DX7II / TX802 LFO multi mode does not work?
|
As you may know, the DX7II and TX802 LFO's have a "single/multi" setting. According to the manual "multi" means that each voice gets independent voice LFO. I am scratching my head here because I have both a DX7II and a TX802 and toggling the LFO mode from single to multi does... nothing? Say you put a "saw down" LFO on the carrier amplitude (LFO AMD 99, OP1 AMS 7) and you use a long envelope release. With independent LFO's, you should hear an echo effect. Rythmically distinct notes should remain distinct when the LFO opens and closes the amplitude. This is not what happens: all the "echoes" are synchronized. It sounds just like you would expect "single" mode to sound, and indeed nothing changes if you change LFO mode to "single". Here is an example patch that shows the problem. Am I missing something? Is there a special trick to get the multi LFO to actually work as described in the manual? |

OK I think I can answer my own question. I opened up the DX7II sysex documentation. Table "5-2. Additional Parameters (ACED format)" describes voice parameters that are in the DX7II but not in the original DX7. Parameter 13 is called LTRG and its description is "LFO key trigger (delay) single/multi". That sounds like the "single/multi" setting refers to the LFO delay function and not to the LFO phase. I tried it out and that is indeed the case. If you set a long LFO delay you can clearly hear it. LFO "multi" mode means that each LFO has an independent delay envelope. The LFO phase itself is still global i.e. the same across all voices. Op do 3 okt 2024 om 00:15 schreef contact via <contact=[email protected]>:
