DIY Peaks (White Magpie)

Peaks provides 4 different functions in a small 8hp package: ADSR, LFO / Tap tempo LFO, and a drum synth.

Their common point? They are all about generating an audio or CV signal in response to a trigger and are all focused on rhythmic works.

Peaks is a dual-channel module – making it very useful for duophonic patches or for controlling/synthesizing the kick/snare rhythmic backbone of a patch.

Features

Four in one...

ADSR Envelope Generator

• Segment durations range from 0.2ms to 8s.
• Quartic attack, exponential decay, exponential release.

LFO and Tap-Tempo LFO

• 0.03 Hz to 160 Hz.
• 5 basic waveforms: square, triangle, sine, stepped, random.
• Waveform variations and morphing for each of these: PWM, slope, folding/harmonics, step size, interpolation.
• Phase at reset control.
• Tap LFO can lock onto irregular rhythms.

Drum Synth

• Channel 1: 808 kick model with extra parameters (tune, punch).
• Channel 2: 808 snare model with extra parameters (tune, decay).
• Channel 2: A specific combination of settings transforms the snare into a modeled 808 hi-hat.

Control Modes

• Twin: Channels 1 and 2 share the same parameters but can be triggered independently.
• Split: Channel 1 is edited by knobs 1 and 2, and channel 2 is edited by knobs 3 and 4, with a simplified 2-parameter control scheme.
• Expert: Channels 1 and 2 are completely independent.

Specifications

• Width: 8hp

• Output level: 0 to +8V for envelopes, 10Vpp for LFOs and drum signals.
• The STM32 32-bit Cortex MCU comes already flashed in the kit, using the lastest firmware.

PCBs are produced by synthCube and finished in blue PCB material with a gold immersion.
Panels are designed and produced by Magpie Modular.
The full kit includes the panel, a synthCube PCB, Rogan knobs, Alps pots, all necessary components, mounting hardware, and a power cable. 
Don't worry if you drop an SMT part — for the 0603, 0805, and 1206 packages, we include an extra!! If you don't lose SMT parts, keep the spares to build up your shop inventory.

Important: The full kit is offered ‘on-demand.’ When we receive your order for the kit, we will prepare and QC your full kit before shipping. Depending upon demand and availability-  the kit could ship as early as a day or two, or in some cases could take up to two weeks to ship.
