DIY Oscillator using PIC12F1571

video upload by alloutofsync

"I used this weekend to create a square wave oscillator that operates with the PIC12F1571, which is an extremely affordable CPU available for just $0.71 each.

Since it was my first time using PWM, I spent an entire day generating a square wave at the desired frequency. The required settings and their interconnections were so complex to me, so that I had to carefully investigate each one as I went, which was quite challenging.

The next day, I spent working on ensuring that the output sound smoothly followed the CV input. To convert the CV input into a frequency assuming 1V/Oct, exponential calculations are typically used. However, the PIC12F1571 has limited program memory, so I couldn't use a floating-point math library. I had no choice but to approximate the calculation of powers of two using a Taylor series expansion and rely solely on integer arithmetic. Initially, I approximated up to the second-order term, but the accuracy was insufficient at higher frequencies. Eventually, I extended the approximation to the fourth-order term, which gave excellent results.

While testing with the Pico3 sequencer, I noticed that when the RATE was set to the maximum, the output failed to keep up with the changes. Increasing the PIC's clock frequency from 1MHz to 4MHz resolved the issue, and it followed the changes without any problems.

At this point, about 70% of the program memory has already been used, so I'm not sure how much further I can expand. At the very least, I want to implement duty cycle adjustment. If possible, I’d also like to use an additional PWM channel to detune and combine the signals for richer synthesis."

Moog One | Sound Bank Vol. 1 by Synth Universe

video uploads by Synth Universe

"In this video I play custom sounds created for the Moog One synthesizer. I demo patches 1 - 32 from the Synth Universe Moog One Sound Bank Volume 1: a bank of 64 pro quality patches containing a wide range of pads, strings, brass, poly synths, keys, ambient and soundscapes.

Buy the Synth Universe Moog One sound banks here: https://synthuniverse.sellfy.store

Any effects you hear on the sounds in this video are internal to Moog One. I mainly use delay and/ or reverb and several patches use no effects at all. I generally do not use the chorus and modulation effects as they colour the sound too much (in fact my main use of the chorus is set at 0% mix to add gain to a patch). No external processing was applied in the making of this video.

Winter 2024 Fundraising Raffle: One-of-a-Kind $20,000 Eurorack Synthesizer

We are excited to announce our final fundraising raffle of 2024 featuring a one-of-a-kind Eurorack synthesizer comprised of 52 modules from over 30 Eurorack manufacturers located in 10 different countries. The system, curated by modular synthesis educator Chris Meyer, was inspired by Bob Moog's legendary Moog modular synthesizers in mind. It has a retail value of $20,000.

The system features:

3 Analog Oscillators | 2 Digital Oscillators | 8 Filters | 3 Percussion Voices | Spring Reverb | Analog Phase Shifter | Vocoder/Filter Bank | Frequency Shifter | Digital Multi-Effects | Moog-style Analog Sequencers | Wood Encased Keyboard with MIDI Interface and Arpeggiator | Custom Black American Walnut Cabinet with Chromaesthetic Lighting |

All modules and other components were donated by the manufacturer to make this raffle possible.

Tickets for the raffle are $20 each, 6 for $100, 14 for $200, and 40 for $500

The raffle ends on Friday, December 20th, and is open internationally.

Proceeds from the raffle benefit our important work in science education, archive preservation, and the operation of the Moogseum in downtown Asheville, NC. The Moogseum continues to be challenged by the long-term financial effects of Hurricane Helene, making this year-end fundraiser critically important.
