Jamming on the Arduinome with mlrv

I wile away many an evening jamming out loops on my Arduinome with mlrv, so I thought I'd capture a little on tape.

Each track in mlrv holds a sample, and relates to a horizontal button row on the Arduinome. The sample is sliced up in to sections, and my Arduinome controls the triggering of the first 8 sections (since it's only 8 buttons wide). mlrv has a basic loop recorder that I use at the beginning of the video to capture the baseline.

This was recorded by piping the output of mlrv to Soundflower, routing Soundflower in to Logic, capturing mlrv with iShowU, and editing in Final Cut Express.

I'd love to send you a saved copy of this file, but the version of mlrv I'm using has a bug and it doesn't save. Since I don't want to fork out $700+ for a copy of the Max/MSP editor and I've never been able to find an mlrv version that worked properly, I just live with it being busted.

If you happen to find a working version that saves, send me a link and I'll get you a copy of this file with the associated loops.

You have to set the appropriate port in ArduinomeSerial.

1. Hit the /mlr button in the bottom right of mlrv while ArduinomeSerial is running and it will set it for you.

2. Make sure that the protocol in ArduinomeSerial is OSC and not MIDI.

3. In mlrv, press the DAC button to start the digital audio

After you hit the DAC button then your monome should show a flashing light in the top corner to show it's connected. Good luck, it takes a bit of figuring out the first time.

Nice. Was that $35 for all 3, or $35 each? Who did you order through? Let me know if the PCBs are any good.

I ordered my unsped shield from BatchPCB.com. It's on the parts list on my blog with a link to the Eagle file that you need to submit to them. I paid about $35 including shipping, and the quality of the PCB was very good.

I could never get ahold of xndr from machinecollective. Shame, really - I can understand him packing it in, but it would have been nice of him to open source the hardware spec for his cases before doing so. That said, I like my curiousinventor case.

Oh, firmware is also a piece of cake - I have that all on screencast, so I'll try to get that done and posted as well.

The wiring is actually not that bad at all. I kind of went overboard with header connectors for the wiring because I'm a little OCD and I wanted the wiring to look clean, which made it more work than it needed to be.

If you follow the curiousinventor build guide like I did, they have great color-coded diagrams that make it almost impossible to screw up. If you go with the other board I won't be able to assist as much since I went with the SparkFun PCBs.

dude. can you send me the saved file from mlrv you used here? along maybe with the samples also. - modi.ankkit@gmail.com

i have arduinomeserial how do i connect it to mlrv?

I ended up doing my Unsped PCB from another source, but I'll be getting 3 copies for around $35. I figure i can hold the other 2 as reserves in case I mess up, or I can even sell them back to the arduinome community or build another one.
