MB firmware compatibility with Arduino 1.6.0

Alpha, Bravo, Delta, Multiboard, , , ,

I’ve discovered to my shock that the type definition “prog_uchar” that I’ve been using to place data in SRAM has been deprecated in the latest version of the IDE (Arduino 1.6.0). It means that most of the firmware for the MB won’t compile in the latest IDE!

While I update the code, the work-around is to not use Arduino 1.6.0, but instead to use the version before – Arduino 1.0.6.  I’m working on a fix as we speak.

UPDATE

Done! 2015-03-13

And the latest IDE versio is no 1.6.1

Syncing the Groovesizer Alpha to Reaper

Alpha

Here’s a step-by-step guide for syncing the Groovesizer to Reaper.

  1. download the drumloop at http://www.freesound.org/people/Th3R3m1x3d/sounds/106552/

  2. create a new project in Reaper (File/New project)

  3. import the drumloop (Insert/Media file)

  4. in the track view, grab the right edge of the drumloop clip and use alt+drag to the start of bar2. this time-stretches the clip so it’s exactly a bar long

  5. copy and paste multiple instances of the drumloop clip so you have a good long stretch of drums and loop the section for good measure

  6. make sure you have a MIDI cable connected from your audio interface’s MIDI OUT to the Groovesizer’s MIDI IN

  7. Go to Options/Preferences/MIDI devices

  8. under “MIDI outputs to make available”, double-click your audio interface’s midi output

  9. on the “Configure MIDI Output” window that pops up, select both “Enable output to this device” and “Senc clock/SPP to this device”Reaper Sync

  10. when you press play on Reaper now, the Groovesizer will follow along in sync

  11. the offset appears to be different every time, so you’ll have to ensure the Groovesizer’s first beat aligns with the first beat of the bar in Reaper manually by pressing F1 on the Groovesizer (see the video below). Once aligned, it will stay in perfect sync until you stop playback.
