Chameleon Modular Synthesizer - Ceylon Quad Channel Sequencer


Published on Dec 26, 2019 Johan Bilén

"This is a demo of Ceylon, my quad channel sequencer. I'm using two channels. Channel one sends notes to the Namaqua-module and channel two sends data to Namaqua filter frequency cutoff of its right channel. The clock is generated by an LFO from a Senegal module."

See the Chameleon label below for more.

Chameleon Modular Synthesizer


Published on Nov 6, 2019 Johan Bilén

"CHAMELEON - MODULAR SYNTHESIZER specifications:

This synth is made up of four individual Chameleon modules.

Software files used:
Slot 1: NAMIBIA
Slot 2: NAMAQUA
Slot 3: TIGRIS
Slot 4: JACKSON

MIDI IO with channel select and MIDI clock out. Note, velocity, pitchbend and modulation wheel output.
Arpeggiator with external or internal sync. Up, down, up/down or random pattern.

Chaos Designer randomizer with external or internal sync. Range, speed and variation adjustable via performance controllers. Note (0-112) or frequency (0-2048) output.

DCO x 4 with individual stereo panning, mixer level and semitone tuning. Pulsewidth modulation and FM. Nine waveforms (Sin/Saw/Sqr/Ramp/Tri/Pulse/WhiteNoise/PinkNoise/FM). Manual mode where each oscillators frequency is adjusted via performance controllers. Legato between 0-635ms.

DCF x 2 with link function, two individual mono filters or one stereo filter. State Variable Filter with Low, Band and Highpass filter. Resonance and manual frequency adjustable via performance controllers.

DCA with external control and bypass function.

ADSR x 2 with fast, medium and long mode.

LFO x 2 with fast, medium and long mode. Four waveforms; triangle, sawtooth, square and S&H. Cycle end indicator via gate jack. Rate controlled via data input jack or performance controller. Amplitude controlled via data input jack or parameter value.

56 point modulation matrix with 14 gate input jacks, 14 gate output jacks, 14 data input jacks and 14 data output jacks.

Audio Interface with 4 audio input jacks and 4 audio output jacks. Daisy-chain function where the audio inputs are routed and mixed directly to the audio outputs.

About the Chameleon System

The Chameleon System consists of a hardware module, a Chameleon, that can be flashed with software files to decide its functionality.

There are two types of Chameleons:

* CHAMELEON.SONIC MODULES
This is a module equipped with a MCU as well as an audio shield. This module is for files that handles audio input or output, such as oscillators, filters etc. So far I've written these files:

• PANTHER Digital Synthesizer Module.
• NAMAQUA Four Oscillator Module.
• TIGRIS Stereo Filter Level Shaper.

SPECIFICATIONS:
ARM Cortex-M4@180MHz, 2-channel audio I/O, 3xC11D I/O, 3xGate I/O, TFT 2.2"-screen, Four potentiometers, One rotary encoder.

* CHAMELEON.SIGNAL MODULES
This is a module equipped with just a MCU. This module is for files that handle data manipulation, LFOs, envelopes etc. So far I've written these files:

• NAMIBIA MIDI Input/Output and Data Randomizer.
• JACKSON Quad Function Generator.

SPECIFICATIONS:
ARM Cortex-M4@180MHz, 4xC11D I/O, 4xGate I/O, TFT 2.2"-screen, Four potentiometers, One rotary encoder.

POWER DISTRIBUTION
Power is supplied to a Chameleon connected to power via its USB-port.

DATA COMMUNICATION
The Chameleons communicate with each other using standard 3.5mm cables sending and receiving 11-bit data. I call this technique C11D or Controlled 11-bit Data as a digital equivalent to CV, Controlled Voltage. Values between 0 and 2048 are sent and received. A unipolar parameter subtracts 1024 from the incoming value making it possible to modulate between -1024 and 1024.

PERFORMANCE CONTROLLERS
The four analog potentiometers on each module work as controllers for real-time control of key parameters.

PCB DIMENSIONS 100x100mm."
