Hello everyone,
I've hit a wall in SynthMaker. I am having a problem taking a float array, and outputting it to a mono output.
Here what I'm trying to accomplish:
1) Taking the input audio and placing it into an array
2) Resampling smaller subset arrays from the input array
3) Output numerous of these subset arrays
Obviously, it's step 3 that is giving me the problems.
Any advice or links to external documentation on this "float array->output" problem would be great.
Thanks everyone,
Corrado

You could try using the "Float Array to mem" primitive, of maybe the "Float Array to Poly" primitive (you can later convert the poly to mono).

I wouldn't have thought it that obvious... steps 1 and 2 are not trivial either.
FA2P might work but how big are the arrays? (...and you have to sort out the index input).
What are you doing with the data in step 2? Maybe there's a way to avoid arrays altogether.

I gave that a shot. I can get the float into memory, though I can't seem to move it from memory to output. Haha.

Basically what I'm trying to do is make a simple granular synthesis program.
On a midi note-press, I have it creating a wave, then storing n amount of samples into a large array. From that large array (called a Window), very small "grains" of sounds are taken from that large array.
For example, the window can store 1 second of audio, so the array can be up to 44100 samples. A grain can be created that is anywhere from 5ms of audio to 100ms. Which would make the smaller grain arrays approximately 200 samples to 4410 samples.
It's those smaller grain arrays that I would like outputted.
I've attached my file, hopefully it will make sense.
Thanks again for all this help.

Hmmm... Yes, that is definitely interesting. I see how they kept everything as a poly. That's probably the proper way of doing it. Thanks for that link.
