Thank you for replying! My ARP 2600-V behavior is not consistent, yet the default patch (when ARP 2600-V first opens) "Groover_Seq" hasn't worked in months (within Cubase LE4), and rarely do any of the sequencer patches work. Usually, the G.Darcey Bass patch "GTD_BaktoBasic" works, but sometimes that doesn't have sound along with all the other patches. This morning, I initially couldn't get sound from any patch, then I removed the track from Cubase, started a new track, then I got the "GTD BaktoBasic" patch to work, and very surprised a few of the sequencer patches actually worked, but most didn't. Later on, the same sequencer patches didn't work at all. I just tried the stand-alone ARP 2600-V, and all the patches work fine. Once in awhile (but not often), I get patches in minimoog-V that have no sound in Cubase LE4. Maybe it's a Cubase LE4 issue. Though I rarely have this issue in CS-80V, Jupiter 8V, Prophet-V, Moog Modular-V within Cubase LE4.
