Meggy Synth - Demo

flickr By sean_carney
"Meggy Synth is a sketch I wrote that allows the Meggy Jr to act as a simple step-based synthesizer for writing 8 bit music.

The sketch allows you to write music over a three octave range using anything from whole notes to thirty-second notes with optional slurs between notes. This video shows me writing a scale in pitch mode, switching to duration mode to set the length of the notes, then playing the song back in both pitch and duration view so you can see how the modes work together.

MeggySeq 1.0 Released

You can find the full details here

"MeggySeq is a step sequencer for the Meggy Jr. RGB from Evil Mad Science

MeggySeq does not make any noise itself! It sends values over a serial connection to another device. I have built it to talk to an Arduino with a Wave Shield attached

MeggySeq has 8 patterns of 16 steps each. You can set each of those steps to play one of 8 WAV files on the waveshield. You can play the pattern back, stop it playing, and change the tempo. You can copy patterns from one slot to another. You can even save all 8 patterns from RAM to EEPROM so they won't be lost when you turn off the Meggy Jr.

You can loop patterns into longer compositions (up to 8 patterns long) and edit the patterns and pattern parameters (like tempo, loop length, and pattern length) without stopping playback.

You can edit one pattern while another is playing, and if you change patterns during playback, the first pattern will finish playing before jumping to the newly-selected pattern (or the next pattern in the loop if you've turned on looping)."

MeggySeq Loops and Noises

"MeggySeq, Meggy, and the Waveshield with a different set of files. The Waveshield plays files straight off an SD card, so I believe they can be arbitrarily long (up to the size of the SD card the Waveshield supports-- 2GB).

It's monophonic, though, so if something is playing and you start a second file, the first stops playing. This isn't a bad thing, depending on what you're trying to do. It does give you some fun glitchy possibilities. (The loops and samples are from www.rhythm-lab.com.)"

MeggySeq

"The Meggy Jr RGB from Evil Mad Science running MeggySeq, driving a Wave Shield from Lady Ada. MeggySeq is a pattern-based drum machine sequencer. It has 8 patterns of 16 steps each and each step can play one of 8 samples (the colors are hard to tell apart on the video). Next steps: Saving patterns to the eeprom, sending MIDI (currently it just sends single characters over serial to the WaveShield) and possibly syncing to external clock sources. Or, you know, changing the tempo at all."

"Darius (tinysubversions.blogspot.com) and I have been messing with the Meggy
Jr RGB kit for the past few days. He did some neat stuff last week, and that
led me to order one and build it on Sunday. It's a great little kit-- it's
VERY easy to start doing interesting stuff. He was doing some things with
his MeggySynth and the Waveshield, and I wrote this sequencer in only a few
hours."

MeggySynth Synched w/ Arduino Waveshield

flickr by dariusk
"I've got the MeggySynth synchronized with an Arduino Waveshield, which has been preloaded with some slices of the Amen break. The MeggySynth is communicating via serial port with the Waveshield, and is triggering samples to be played on the Waveshield. The pattern is stored on the Meggy itself, since the Waveshield is sorely lacking in free ROM/RAM.

Synchronization is still a little wonky. But I kind of like the stuttering sound. Other samples (like simple kicks and snares) sound better, but less interesting."

First demo, MeggySynth

"This is my first run of a little live performance sound and video device I'm calling MeggySynth. It's definitely just a proof of concept, I'm hoping to make things more impressive all around.

Again, sorry about the disappearing pixels, it's the aliasing from the refresh rates of the Meggy and my camera."
