Granulators

[unguitar]

Granulators ( like for example the one in Audiomulch or some more complex ones like the excellent Melda Production's one) are for sure the most interesting algorithms I have found in software processing.

Is there anything like this on the H8000 ?

I know all you need to make one is in the machine already but I my Vsig skills are far from being recovered to reach such level of audio engineering…

That's something I'd also like to explore and learn about in depth on this system.

I think of granular synthesis as reading many concurrent short samples of audio from a larger sample file.  The short samples' read position, pan, pitch and amplitude are all independently variable and have a measure of randomness.

That's quite a programming challenge to start with !

I might explore the SAMPLER module – it certainly has all the control inputs you could want – start time, stop time, pitch amount, fade in and out times etc. very complex though. I suspect something more lightweight would be better. Perhaps starting with a combination of delays and pitch shifters would be realistic?

There's the EASYTAPS module which is very good to get started with. It has delay times from zero to 650 millisecs with built in randomizing and up to 64 multiple taps out.

Here's a basic example, I'm just learning too!

HEADM adc 2 2 easytaps-left easytaps-right "Easy Taps" Empty 2 easytaps-obj rlfo-obj ;=264,-78,100,0

RLFO rlfo adc-null adc-null adc-null 1 1 1 0.5 0 0.1 ;=138,108,100,0

A_TO_C a_to_c rlfo-out ;=288,108,100,0

C_TABLE c_table 2 a_to_c-out 20 80 ;=426,96,100,0

EASYTAPS easytaps 64 adc-in1 64 c_table-out 0.5 0 1 0 3 0 5 ;=612,6,100,0

Great to know you share this interest !

Bad Acid Jumble is a preset that is worth investigating as well.

It offers just a very superficial set of controls but I think most of what we're looking for as a starting point is there already:

Hey that's great!

Lots of delays running into the ISWITCH selector which picks a random input.

Ideally some control over windowing of each input. But there's potential there for sure.

[unguitar]

yes, some more control options would be fine.

keep me informed whenever you are developing this.
