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."

Bastl Kastle Arp #23 (with Kastle DRUM and tonic)

"I created a rhythm pattern with tonic that evokes a sense of ancient times. On top of that, I intentionally added inorganic noise percussion from DRUM and a melody from ARP. The performance itself is improvised. In post-production, I added reverb and delay.

"This is a short tutorial video introducing a simple patch for the Kastle Drum. It features a basic rhythm with just two sounds, but there's room for further development. I hope this video will be helpful for those who are new to the Kastle Drum or still figuring out how to use it.

Anyway, I hope you enjoy. Thanks."

"The great thing about the Bastl Kastle is that you can patch wires however you want and have fun jamming with it. This is exactly what it's all about.

"The great thing about the Bastl Kastle is that you can enjoy improvising without any pressure, simply by patching the wires as you feel and turning the knobs."

ARTURIA MicroFreak #2 (with PO-12 rhythm)

"Learning how to sync with other gadgets.

I’m using the ARTURIA MicroFreak as the clock source and the PO-12 as the follower. The MicroFreak allows you to adjust the clock resolution, making it highly compatible with various gadgets. You can change the clock resolution from the utility menu.

Anyway, I hope you enjoy. Thanks."

ARTURIA MicroFreak #1 (with TC Electronic T2 Reverb)

"A combination of MicroFreak arpeggiator and T2 reverb.

I finally started using the MicroFreak after letting it sit for exactly a month since it arrived. Skimming through the manual, it seems to have a variety of features. Since none of my other gear had an arpeggiator, I decided to start by playing around with it. By tweaking the analog filter and adding reverb with the T2, it creates a dreamy sound.

Anyway, I hope you enjoy. Thanks."
