Details on BugBrand's new Chirper Semi-Modular Mini Synth

You might remember the video of Chirper posted here. Full details are now in:

"Chirper is a semi-modular arrangement of two oscillators and one filter - a simple setup which belies the rich sonic surprises contained within. It is a direct continuation of Molnet, which itself was something of a reaction to my long-evolving Weevil works - after 10+ years I was feeling the call for new pastures and, while I enjoyed their deep electronic ecosystems, the lo-fi Weevil circuitry was never suitable for voltage-controlled work. The solution was to tweak ideas I'd been using in the SynthVoice, slightly simplifying some circuits to bring about an instrument with enticing layout and a fine balance of limitation vs. possibility.

Have a look at the Block Diagram above to see how Chirper is put together:

- the two Voltage-Controlled Oscillators are identical, with wide range (approx 0.15Hz to 100kHz) and sweepable from Triangle to Square.

- each oscillator has a Sync input along with Internal (from the other oscillator) and External (1V/Oct) Modulation controls. Things go nutty when the oscillators cross-modulate each other!

- the Voltage-Controlled Filter, with resonance up to self-oscillation and sweepable from Low-pass to High-pass, is fed audio from the 1st Oscillator (via Drive control) and is modulated by the 2nd Oscillator and/or an External (1V/Oct) source.

Of course, there is no internal VCA, so do be prepared for drones! [complimentary modules are in the pipeline] Note also that the 1V/Oct responses of the Oscillators and Filter are only quite accurate - fine for good tracking over a few octaves - and does not feature temperature compensation. Chirper was designed more as a surprise box than a well-pitched synth, but I saw it as a bonus to add simple 1V/Oct response.

4mm banana sockets are used for all I/O other than the Main Output which is 1/4" Mono Impedance Balanced. The Instruction Sheet has details of interfacing with banana cables.

Interface and/or banana cables are available.

Chirper is typically supplied in Standalone form as shown - enclosed in a custom aluminium case with PCB material front and side panels, dimensions approx 5.25" x 7.5" x 3.5", and with internal DCDC converter. Power - 12V DC 300mA supply, centre-positive, 2.1mm connector - worldwide 90-240VAC wall-wart provided with interchangeable mains plug adaptors.

Price: £320 (+VAT in EU -> £384) + Shipping

Chirper can also be supplied as a module to fit into larger BugBrand systems using Powered Frames - make contact direct.

The module draws approx 55mA per side.

Module Price: £280 + VAT + Shipping."

New BugBrand Board Chirper

Published on Jan 25, 2019 BugBrand

"Some sonic demonstrations of the new Board Chirper - live video mic."

"A year after the original Chirper, a new 'Board' version arrives in compact and touch-plated form - welcome the Board Chirper!

Like the big brother, the Board Chirper is made up of just two oscillators and one filter - a simple setup perhaps, but which contains a surprising depth and quality of exploratory sound.

Oscillators:
- Range of approx 0.1Hz to 40kHz
- Sweepable from Triangle to Square
- Cross-couple modulation between the two oscillators

Filter:
- State-Variable 12dB/Oct with resonance up to self-oscillation
- Sweepable from LowPass to HighPass
- Variable input drive control from Osc1 (left side)
- Cutoff modulation from Osc2 (right side)

- Level control feeds transformer-isolated 1/4" mono jack output
- Powered by single 9V PP3 battery (included)
- 19 gold-plated touch points
- one year parts warranty

The Board Chirper is presented as an uncased design on blue PCB measuring approx 8.5 x 5 inches.

Price: £160(+VAT in EU -> £192) + Shipping"

"All these are brand new accept the compressor
Which I bought from Josh @ Malekko.

Chirper not in the system. That’s just a faceplate to fill space. Includes dual filter, dual amplifier and dual mixer.comes with extra Bugbrand Blank panels for DIYing. You can see that they have guide holes for
Mounting your DIY stuff neatly. Pretty cool concept.
1-space and 2-space blanks included.

This is a great way into Bugbrand. It’s an instrument in its current form with just enough room to grow. The GRILLES and TRESSES are Bugbrand format modules from Batchas on MW.

Includes 10 banana cables, PSU and system.
Willing to sell the compressor module separately for $600"
