Works in your browser, samples don’t get uploaded
so I got my OP-Z today and was super impressed and happy until I tried getting my samples on it.
I couldn’t believe it at first, but I spent a lot of time and confirmed it: it really is not possible to get samples on there that you can play on the chromatic tracks without using an OP-1.
You can use OP-1 Drum Utility to create a drum sample pack but no synth sample pack.
Synth samples exported from an OP-1 work fine but no chromatic custom 14 16 mono aiffff samples. Dreams were still dreams.
I couldn’t live with this situation so I started digging and found a solution: AIFFs can have custom chunks and the OP-1 inserts a special chunk for controlling the settings for synth samples. There’s a bit of documentation about this here: Op 1 Application Chunk format · operator1/op1 Wiki · GitHub
The file I took for reference had a JSON string inside of this APPL chunk:
So what I did: I opened my own custom AIFF file in a hex editor, located the SND chunk, pasted the whole AAPL chunk from the reference file before that and voila, the sample would now be loaded after being put on the disc in OP-Z content mode.
I think I’ll try and write some little software that does this automatically if there is any interest.
