This is a two part Live stream where I build the Synthrotek MST Dual Envelope kit.
This kit is available from Synthrotek’s Store. You can grab this in kit form as seen here or as a completed module.
The Stream is completely live and I take questions and discuss not just the process of building the module but we talk synths in general. so sit back, and enjoy.
Part 1
I will have a in studio demo/ review video of this module up shortly as I have since built one of these modules for myself and am very impressed with it. in the mean time check out the synthrotek store and grab one of these very handy modules. Synthrotek ADSR in Store
The MST MIDI to CV Converter is a translator between digital devices and analog synths, allowing you to connect your modular system to a keyboard, computer, phone or tablet. Continue reading
USE ALL OF YOUR LIMBS!
The MST Expressor allows you to use expression pedals with your modular, taking a “hands-off” approach to expand your control and creativity. It has two identical powered expression pedal processing units in one handy module, allowing you to do things such as: Continue reading
The MST Dual Envelope is a simple-to-use yet complex dual envelope generator. Channels 1 and 2 are both normalled to each other to cycle when the other respective channel hits end of cycle, allowing for really interesting ping-pong effects. Each channel also has an end-of-cycle trigger output with LED indicator. There’s a normal and inverted envelope out. The inverted envelope out can be further modified by the +5 offset switch, which allows the inverted waveform to travel in the positive. The + output level allows the envelope signal to go between zero and the maximum voltage rail. Attenuate the output level down for a more subtle envelope (adjust to taste).
Features:
Two self-completing envelope circuits
AD or ASR selector switch per channel
Manual Attack control & Decay/Release
Output level per channel
Gate input
End-of-cycle trigger output with LED indicator
Normal & Inverted envelope output per channel
Short and long envelope length switch per channel
Long setting can be lengthened with jumper select
AD/ASR selection switch per channel
Inverted output +5 offset switch per channel
Specifications:
Current draw: V+ max 10mA, V- max 8mA
Width: 12HP
Retail price = $224.99
The MST ‘07 Buffered Multiple is a PRECISION buffered mult that is perfect for for 1V/O CV sources. A signal plugged into Input 1 will be available from all 14 outputs. Break the chain by adding a second signal into input 2; signal 1 comes out 4 outputs and signal 2 is available at the remaining 10. Plug in as many as 4 inputs, each split 3 or 4 times. What you put in you GET OUT!
Features:
4 Channels
Channels 1 and 2 are 1 to 4
Channels 3 and 4 are 1 to 3
Cascaded inputs: CH 1—>CH 2—>CH 3—>CH 4
Specifications:
Current draw: V+ max 23.3mA, V- max 23.1mA
Depth: 1.5 inches
Width: 9HP
The 555 Timer Oscillator from Synthrotek will be a modulation source for our upcoming Delay Dev kit circuit. (and other circuits as we will keep this modular!)
the Idea is to use this to modulate the rate of the delay board.
For this project, we won’t be hooking up power just yet as I plan on daisy chaining the power off of another circuit first.
we also will not solder on the attenuator just yet as we will be using wire so that we can place the board more efficiently inside of the case. You can buy the 555 Timer LFO HERE—> Synthrotek Store it’s only $15.
