Op 1 style sampler

#1

Hi folks, ill put this under hardware category, but this also includes some patching.

I was wondering for some time about what should i make out of axoloti and finally got
Some ideas. Im wondering, how one would aproach building op 1 style sampler, by that i mean, sampling from radio (fm, am). ? first thing that comes in mind is that i just plug radio in audio input and use some sampler patch, but it would be more interesting to build custom hardware and patch for it. Is it worth it? It should be. Thoughts? Ideas? Suggestions?

Sparkfun has an FM tuner with serial control here. I'm sure there are other modules/kits like it out there.

I've been interested in that Sparkfun radio module for a while. Intrigued to know if it can be controlled from an Axoloti.

Ill order one, must test this out

Any progress with this? I think it'd be fun.

I think what it makes op-1 sampler peculiars it's the way they work. drum sampler it's pretty well thought with that possibility of importing a whole Kit by just loading a simple 12 seconds sample.. Also the fact that T.e uses "extra" information in the .aif file to specify where are the start/end points per every sample + other info like gain / playmode or pitch per sample. being able to replicate that functionalities would be ultra-dope because its very convenient to organize soundkits in a single file.. Does any of you know if there is an object to locate silences in sample files?. this would be the most tricky part about importing a soundkit and assigning different midi notes to different portions of the sample kit.

I think storing metinformation in samples and reading it out should already be possible. I think @rbrt did so in an earlier version of his looper, where a little tick at the end of loops that were recorded in axoloti and then saved to sd card would indicate stuff like loop length.

thats really cool.. another way to do kits would be to do a "second per sample" rule and add triggers every second. if some samples are longer than 1 sec it's ok, just leave a blank until the next second with a next sample starts.. anyway now I'm researching more into playing long files from SD for audio installations and Axoloti + laser..

that would be an easy and practical solution I guess...

Would be a good Idea to figure out how it is done with the op. Eventually what you're dealing here is just writing metadata into tables and reading it out.
The most relevant thing would be the sample start point I guess. So if you choose that a kit always has 12 slots
you could use the first 12 positions to store the respective starting points. end point would be start point of the next -1.
This would be fed to your 12 sample players.

Sounds dope, looking forward to some documentation of it :slight_smile:
