Hi all. There is a from a little time that im not around here! 😀 My question for help is that; How i can manage to create a drum pattern for wav's, starting for a ramp based LFO. Should be not too complex, just setting correctly samples POS and PPQ pos. The default waveplayer is able to retrive a correct position of sample index and use a correct timing. But i should rewrite that in order to process the ramp pattern correctly. This mean the sample position should be taken from the current PPQ pos, in a correct way. Any advice of what kind of math i should do to syncing that?

The "PPQ to Ramps" module from THIS POST should give you a start. You tell it what note division to use, and how many of them there are in the sequence, and it outputs two ramps - one goes from 0-1 for each division, and the other cycles around the whole sequence. Assuming that you have a loop sample that is accurately trimmed to length, the sample position should be...

Position = Sequence_Ramp / Sequence_Length * No.of samples.

    It goes on the track you’re editing there, in place of that track’s sound, and into My sounds. Your other tracks stay as they are.

    Want to keep that track’s sound? Start a new song in SynthMaker first (Song › New song), then open this.
