[ITP: Designing Your Synth Voice] Group Work??! Yuck

In class examples

Here were some VCV rack examples we did in class 02/12/24. These might be helpful for future Priyanka (or anyone else).

Amplitude oscillation

Frequency oscillation

Envelopes —> ADSR

Sequencer

Quantizer

Also in class we learned about line inputs and outputs. Line level is a standard used typically with gear that has the ability to adjust the volume/gain, such as a mixer or amplifier. It’s approximately 1.75V which is not enough to power headphones. The Teensy audio shield has mono left and right channel outputs.

Assignment

Hi Jesse. This week I organized the Stupid Hackathon and mentally I am here… everybody shut up on this floor. Everybody shut up in this department.

This week I got a new breadboard and a Teensy 4.1 because I realized I would quickly run out of IO pins on the 4.0. A big task for me was soldering all the headers for my new Teensy and getting my buttons and potentiometers set up again.


This was a two week assignment to use the line in/line out pins to patch into another person’s synth setup. I was on a three person team with Tres and Q. This was kind of a brain-breaking practice because I had an untested, brand new setup and I think Tres was having some hardware issues.

We started with the pass through example, which seemed to work for me and Tres. Then we tried to get all three synths working together. Here’s some documentation of us jamming together. Tres’s line out was connected to my line in and my line out was going into Q’s line in. I’m not really sure what’s going on here. Tres has some LFO and modulation going on. I tried getting the reverb example going. Q also had something going on in their setup but the best part was the drum they had setup on the button (you can hear it at the beginning of the clip). Overall, no idea whats going on…

Envelope module

I’m also really curious about building a sequencer at some point, I think. I watched some videos and saw people’s really cool synths they’re making. I’ve linked some inspo’s below for future reference.
