I’m having a hard time finding the module for a pretty common synthesis function: I’d like to load sample and play it back using an LFO, e.g. inputting a 60-hz sawtooth would play the sample from beginning to end once per second, a 60-hz triangle would play the sample once forward and once backward in the same time, et cetera. It seems like this function would by in one of the NYSTHI sampler modules but I can’t find it. Does anyone know how to make Rack do this?
A small note: “once per second” = 1 Hz, not 60 Hz. I only point this out because otherwise -even with the right module/function- you may get unexpected behaviours.
I’m not sure its exactly what you want, but there are a bunch of granular synthesis modules that can do something close to what you are describing - e.g. the Voxglitch Grain Fx is an add-on that provides LFO position controls for the sample.
What I’m imagining would be analogous to using a voltage to control the position of a play head along a piece of tape - a slower upward slope produces slower playback, a downward slope produces reverse playback.
What NYSTHI’s Sussudio does is very much like this, but I’d like to scan through a file using a waveform other its built-in constant ramp from [begin point] to [end point].
I think they want the LFO to control the position of the play head rather than just triggering it to start. I’m using Simpliciter right now though, and I’m not sure which input sets the absolute position of the play head? Maybe if you use both slice inputs at once?
I’m still following all the leads in this thread (thank you everyone!) but I’ve used OUAIve’s Gate Mode to build the patch in my first-ever Rack video, which is here:
This particular implementation is certainly something Sussudio or another sample player could have done, but a lot more possibilities are open…
