Keymatrix to single input

June 20, 2012

I have wired the keyboard as a CV monophonic keyboard. The output from the keyboard goes to an analogpin on the Arduino.Image


I wont even nee…

I wont even need a DAC on the Arduino.

I’ll run PWM on port pin11 with 60KHz to get 8-bit analog output.

So still no extra hardware on the duino.

I have a couple of digital filters but I think they will be unused.

Just get the right waveform and we will have the SuperSaw.

The keys

The keyboard I’m going to attach to this baby Arduino Nano is a 37 mini-keyboard with a 5 x 8 matrix.

What is a SuperSaw wave or sound?

Well, there are as many answers as people answering the question.

The basics is called phase desync or simply chorus and there are many ways to achieve the same result.

The simplest is to use a number of detuned oscillators.

You can use a tight chorus modulated by an LFO.

It can be done with PWM of a sawtooth.

I havent decided yet on the method but I’ll do it for sure.

SuperSaw Synth with the Arduino

June 19, 2012

Hi all.

I’m back after 3years of writing firmware for heatpumps.

Got tired and wanted to do a synth again.

I have always liked the Roland SuperSaw trancesound of the JP-8000.

As I already have a lot of synthesizers I just need that small tabletop synth to give med those nice leads and pads.

How do I get that?

The Arduino 🙂
