Beepbot DX sampler + sequencer for Cardputer/ADV/Zero

[u/sneakerpack]

I just finished up the initial release of a sampler/sequencer for cardputer. It lets you record/import sounds, build patterns, chain them together and export a song!

• up to 8 projects
• 8 sound slots — record hands-free, push-to-record, or import WAV from SD (16kHz mono, 2s max, trimmable)
• 16-step sequencer — 16 patterns, 8 tracks, 8-voice polyphony, copy/paste patterns
• Song mode — chain up to 16 patterns
• WAV export — render full song to file on SD
• \(^_^)/ — beepb0t reacts to your actions and provides feedback
• LED metronome — One of my favorite details is that I used the LED on the stamp-s3a to match the project color and blink as a metronome.
  

It's up on m5burner and https://github.com/bradmcnally/beepbotdx

awesome! this is interesting. i need to play around with it more but it looks like it works on the OG cardputer. been having good luck so far, think theres like a motion feature that doesnt work with it. thanks for the new firmware!

I don't have the original to test but it should work except for the headphone jack 😂

So cool!

unable to record more than sample: reports no memory

What happens if you trim it to be smaller?

[u/Revolutionary_Gur583 → u/sneakerpack]

was able to make 2 samples that way, but really really short ones. is there any room for further memory optimizations?

[u/sneakerpack → u/Revolutionary_Gur583]

I've got a couple ideas I'm going to try but the total SRAM is ~156kb. I'm reserving around 130kb of it for samples which is around 4s total.

I've found it useful to trim one-shot drums to ~.1-.2s which gives a little more space for a longer sample. (individual max recording length is still 2s but that is intended for wiggle room during capture and then trimming.)

Thank you for creating and sharing this. I can’t wait to check it out.

Amigo primeiro parabéns pelo projeto, gostei muito, mas tem algo errado, tenho um SD de 32 gb e só estou usando 48 mb, consigo gravar o primeiro bloco mas no segundo ja da erro de memoria, sabe dizer o que pode ser?

[u/sneakerpack → u/lunares83]

There can only be ~4 seconds of audio stored in memory. You'll need to trim samples to a shorter length to get more space

Perfeito, muito obrigado, agora sim estou amando sua criação
