Add new channel/note to a poly connector ?

Postby Chaoslala on Thu May 10, 2012 3:49 pm

Most time i like to use a lot of pitched poly freq connector with the same oscillator.
So i'm forced to multiply the number of same oscillator..

Is it possible to combine my différent poly connector into one to have the same result ?
So that every new note create a new channel in the poly rather than make addition with
the other one.. ?

a little example in osm:

SM's 'engine' won't let play with polys that way. Each 'voice channel' is always universal across the whole schematic, so you can mix them together (as in, like an audio mixer), but you can't force them to go 'in parallel' with each other. (sorry if that's not too clear, couldn't quite put what I mean into words). In fact, if you were to connect the poly's from two 'MIDI-to-poly' together, SM would get very confused because there would be two lots of notes trying to use the same set of 'voice channels'

There is kind of a way to do it though - but it has its downsides.
The 'MIDI to Multivoice' will let you layer voices (a synth 'unison; in effect) - i.e. to have several new voices all sharing the same note - so one oscillator becomes many, like you are wanting.
The main downside is that everything in your synth is duplicated. You can't just duplicate the oscillators, it has to be with the filters, LFO's, envelopes etc. as well - and that will increase the CPU load.
The other hassle is that it's trickier to set up, especially as your individual layers are going to need their own settings - you have to fiddle a lot with arrays to be able to get at separate parameters per layer.

Don't let me put you off - if that sounds like a viable solution, we can point you at some helpful examples - but duplicating your socillators 'manually' will give you a lot more control over CPU load and the features of your synth.
Feel free to use any schematics and algorithms I post on the forum in your own designs - a credit is appreciated (but not a requirement).
Don't stagnate, mutate to create. Without randomness and serendipity the earth would be just another barren rock.
