Good news: Teensy 3 instead of 2

I have decided to change the heart of my controller. 🙂

The Teensy 3.2 gives much more of all: More pins, more power, better analog control, more space on flashrom, RAM and  EEPROM. I’m thinking about to implement something with touch control.

And there is the oportunity to make a synth of it!

I have to make a new PCB, because the old is not pin compatible and there are now 2 different voltages. But I’m lucky to be able to make an adapter for prototype usage. 🙂 The new voltages are no problem as I have tested all components with them on breadboard. Just some lower resistors, that’s all.

There are so many new possibilities and new ideas, I didn’t thought about as I started my project one year ago as a simple MIDI controller with 64 CCs.

New play mode available: euclidean sequencer

If you not heard about euclidean sequencer:

Euclidean sequencer generates natural sounding rhythms, you should read this:


I have integrated it to the sequencer now and it is a nice, inspiring technique,

especially in combination with the other possibilities of the sequencer like ping-pong-play, chord play, swing and so on… 🙂


My next steps are to include this in the menu and I want to visualise the sequence on the display.

Added MIDI clock and reverse play

Today I have added the internal MIDI clock and reverse play to the sequencer.

So it is now possible to play MIDI instruments without need of an external clock from a computer or clock generator!

Reverse play is the third play mode of the sequencer. As the name says, it plays the notes in opposite order than forward. 😉 Currently, there are the modes forward, reverse (or backward) and random play. There will be ping-pong play at soon, which is a combination of forward and reverse play.

Next steps are to integrate BPM control and MASTER/SLAVE switch in the menu, which will hopefully not overstrain me. 😀
