"this is a sequencer I built with an Atmega arduino chip. the chip basically replaces the CD4017-or the like-but adds a few features like gate controlled reverse and random. The modules also has an offset input so you can use it like an arpeggio. there is no gate output but it does have an externally trigger reset."

"put together this sequencer/arpeggio based on the CD4024 7 stage ripple counter chip. rather than stepping through each channel like classic sequencer, the channels add in different combinations according to the binary nature of 4024. Module features an input to represent the "0" state which is supplied by my 10 step sequencer (to the left)."

"using a CD4024 ripple counter as a sequencer makes an interesting arpeggio circuit. very fun."

"This is a portamento module I designed and built. It's based on a Harry Bissell design for seperate attack and decay control portamento. I added a gate controlled on/off switch. it has separate 4 channels. and I etched an image of Ziggy Stardust on it as nod to Attack and Decay also being called Rise and Fall."

Fun sequence!

"this is a little fun demo of a portamento module I've been working on. It' has separate controls for attack/decay (rise/fall) as well as a slope adjust between Linear and exponential portamento. it's a modification of a Harry bissell design. I added a gate controlled switch for engaging the portamento."

"quick demo of a gate sequencer module I designed around the CD4017. I etched a picture of Rick Moranis on the front of the module. It utilizes a diode "and gate" I borrow from the yusynth clock divider module and a circuit similar to the ken stone gate to trigger for external reset."

Sub oscillator square wave module -- Charlie Slick -- Sagittronics

Published on May 17, 2013 Charlie Slick·75 videos

"This module will create 3 sub octaves from any supplied frequency. The module isn't an oscillator itself, it's only a clock divider with a built in mixer and DC offset. based on the 4017 decade counter chip."

"a demonstration of a simple sequencer I built, based on the 4017 chip, 'baby sequencer' schematics, and a MFOS sequencer schematic. The sequencer is controlling the picture of 1 oscillator and the cuttoff frequency of my synthesizers.com state variable filter. The speed and gate is controlled by a 8038 LFO module I built.

incidentally, my kettle started to boil by the end of this video."
