ALM Busy Circuits Quaid Megaslope

The Quaid Megaslope is ALM Busy Circuits' expansive modular take on a complex envelope generator a la the Casio CZ series. It continues ALM's legacy of creating simple and intuitive modules with astounding functionality, and is sure to become a go-to modulation source in any Eurorack setup.

The Megaslope consists of five stages, with a slider used to determine the ultimate level of each stage and knobs to control the shape of motion to the next stage and the amount of time the transition takes (from ultra-snappy to glacial), along with CV control over both Stage Level and Time. In Envelope mode the Megaslope is a triggerable 5-stage envelope where any stage may be sustained using the Gate input, while Loop mode turns it into a five-stage LFO with retriggering and Step mode allows for the creation of 5-step sequences with adjustable slewing per step. Bipolar and Unipolar voltage outputs and End of Stage and End of Cycle trigger outputs blur the line between mere envelope and monolithic modulation powerhouse still further.

ALM MCO & Quaid Megaslope Modules
ALM's MCO is a digital wavetable VCO with 10 waveforms inspired by 90s hybrid synths which hard harsh aliasing oscillators. We rand the MCO through the MUM M8 filter. The Quaid Megaslope is a powerful function generator based on the function generators from the Casio CZ series of keyboards. It can be an envelope, LFO or sequencer with control over timing, shape and level for each stage. Dinky's and Akemie's Taiko create the drums and the Malekko Varigate 8+ is sequencing everything.
The ALM ‘QUAID MEGASLOPE’ is a five stage function generator or modulator which operates in one of 3 modes.

This tutorial covers each of the 3 modes and shows off various patching ideas. Create complex five stage envelopes (with a looping sustain phase), super controlled LFOs and CV sequences with per step glides. Per stage level and time CV inputs plus EOS and EOC trigger and uni/bipolar CV outputs make Quaid easy to deeply integrate within your modular system.
