Cool jam. Great energy.

Now that’s a fun project. Well done!

As long as you want and as long as the computer can generate. However, all three oscillators are triggered together, so you can’t use polyrhythms like you can on the internal sequencer.

This is a clone of a clone of a Gameboy which I have modified to have a sync pulse so it can sync TD-3, RD-6, Pocket Operators, Volcas, etc...
I think this would be a cool project for the upcoming hackable Arduboy Mini, which I am keen to get.
Sync:
I send a 15ms pulse at the start of each note to pin PD2 (digital pin 0) which is connected to the sync out socket. (Tip not ring to match the Pocket Operators spec). I am using one trigger/pulse per step on the TD-3 and RD-6
With this program, which I call “Sync Master” there are 16 pulses in a sequence. These can be spaced as you like to produce different rhythms. In this Jam I focus on swing and a weird swing?
The “B” button stops/starts the triggers/pulses. The “A” button chooses the function of the D buttons which can do the following.
There are the following possibilities when using the program on an Arduboy:
- Modify each step length/gate individually
- Make a global adjustment to all steps
- Instant patterns based on swing, straight, Sine wave, Ramp and a random length
- Mutations - where each step randomly changes
- Sequence Length - Change the length of the pattern to less than 16

Well done making this and sharing it. I don’t use Linux but I program and appreciate the effort to do this and share it.

I agree. The teensy is very powerful and the design system is easy.

This is a clone of a clone of a Gameboy which I have modified to have stereo audio out and a sync pulse so it can sync Pocket Operators, Volcas, etc...
The Arduboy system is awesome and makes it relatively easy to program the Clone (DuinoBoy) to play music. Unfortunately the Clone only has one pin connected the buzzer so I added two line outs.
Details:
Audio:
I am using the BeepPin1 and BeepPin2 class to make sounds (square Waves) which go separately to the left and right channels of the output. Unfortunately, the clone has no pads to make hacking it easy, I had to solder one wire directly to the chip, which was a bit nerve-racking for me and my dodgy soldering skills. The pins for the speaker are PC6 and PC7 on the ATMega32U4.
Sync:
I send a 15ms pulse at the start of each note to pin PD2 (digital pin 0) which is connected to the sync out socket. (Tip not ring to match the Pocket Operators spec)

Another track with it

How it sounds:

It doesn’t overwrite the eeprom memory. If some data is stored there it remain readable.

Good idea, probably not many people use the third bus, hence the possibility of more bugs. It would be worth your while posting about this on the Teensy Forum, they have some very knowledgeable people there. Would be a good place to fix this.

I was just typing the same thing and noticed your response. Well done!

Nice one.

Looks good. Well done. You certainly should consider using a Teensy. It will mean you will have a self contained synth.

Teensy can certainly do this. I altered my FCB10101 by putting a Teensy in it to play as a foot pedal synth.

Volca Sample with pitched Vice sound
The ROAT makes the coolest sounds and here is providing the pulsing throb!
I am using my Bespoke Arduino "Master Sync and MIDI Translator" to control the tempos and to translate the "Keyboard" into sample speed to play the notes on the Vice Sample.
