Month: February 2010

We’ve been working on the internals quite a bit. This revision deals with some of the newb-ily named OSC messages. This doesn’t handle all of the problems, but it does take care of the significant issues with the step matrix.

Steppa v0.39

• changed the OSC namespace to be prefixed with /beatseqr … look in stepcomm if you need to change that
• overhauled the (8 individually configured files) rosco-row system to the (1 file) roxor_row system
• moved all velocity and midi note num processing to stepcomm

Roxor 2.5 is available, look for the link inline with this post. changes:

• revamped the OSC namespace overall to include the "/beatseqr" prefix
• also significantly revamped the /matrix OSC namespace. I was originally looking at mirroring the way the Max5 matrixctrl object takes in data, but decided against it in favor of a significantly easier /matrix/[row]/[column]/[step] value method. This made is a lot easier to revamp the way roxor handles the step data. But that’s another update for another post.

Derek and I have been hard at work making some really great improvements to the beatseqr firmware and steppa sequencer. Here are a few of the things we’ve been doing lately:

• I added a really nice feature that we’re calling “voice trigger indicator” … essentially what it does is flash the voice select LEDs as your sequence is running to indicate to you when each of the 8 channels is triggering. It’s easier to show than to tell, so I’ll get to work on a video for that asap.
• Steppa now has a “current beat” set of indicator LEDs on the front interface. This was added so you can get an idea of where you are timing-wise if you’re doing stuff on your computer (instead of looking at the hardware, which will give you a *really* good idea of that all the time 🙂 )
• There’s been a bunch of minor features added to Steppa that mostly facilitate being able to pick up sequence data from within Max5. If you’re a max user, you can do all kinds of crazy stuff with the sequence as it’s running.

More good news while we’re talking about good news:

• I have applied to exhibit at the Bay Area Maker Faire. We’re considering applying for Detroit and New York too, so if you want us to apply for those, leave a comment!
• The arduino mega firmware is now open source. There are a bunch of things you would need to do in order to get started and I’ll highlight those in another post soon. I’ll update the license to indicate my intentions, but in a nutshell you’re free to download, analyze, improve, or modify the source, as long as you don’t resell it and you keep the original attribution intact with the code. Please do improve the software. 🙂 I’m a school-trained artist first and a self-taught engineer second. http://github.com/stevecooley/beatseqr-software
• Derek is going to our local ninja academy! Very exciting. 🙂
