A Towel For Ms Winters

"Large format modular synthesizer recording live in the studio.
The opening noise burst is the Dove WTF in noise mode along with the Sputnik WCRS to an Oakley SVF in band pass mode to the Modcan 73B dual Delay and Z-DSP with Halls of Valhalla reverb. Modulation to the 73B is from the STG Voltage Mini Stores for delay cv.
Noise cacophony part is a pair of STG Soundlabs Oscillators to the Oakley Sound Systems Ring Modulator to a Grove Audio LPF and a MegaOhm Audio MA20 in highpass mode. The signal is sent to a tape echo then compressor.
The echo drone bass is the dotcom Q169 vco to a Moon 517S LPF. The echo delay is a stereo Lexicon MX200.
The lower bass tone is the Woven Spirits (MI Plaits) from Synthetic Sound Labs. Straight in, no filter or envelope. The chords are a pair of dotcom Q206 vcos and a pair of Q106 vcos for four part harmony. The cv source is the dual Matrix from SSL in dorian modes. A pair of dotcom Q171 and Q172 Quantizers were used with gates from the Geo-Gruvn to time the S&H pitch voltages. Toward the latter half of the piece I was playing the quantizers to change modes from augmented to diminished and back again. The audio signals are sent through a LWSS Yusynth panning mixer then a pair of filters. The Dove D502 in low pass four pole and the Frequency Central System X in 24dB low pass mode. They are sent to the Empress Reverb pedal in blue sparkle mode.
All gate timings were provided by the SSL Hagiwo Geo-Gruvn sequencer and the STG Time Divider. Additional divider s are the Moon 564, Moon 563 and STG Trigger Mini Store.
The theme here was the well known stories of the femme-fatale-gone-awry roles Shelly Winters played in many famous movies. She was drowned a few times and it became an urban legend of sorts. A great actress that rarely was rewarded with much favor but did finally reach a celebrated status."

MOD2 Prototype test | Seeed XIAO RP2350 based Drum module for eurorack

video upload by HAGIWO

":Almost all of the programs were generated by ChatGPT.
Since the circuit has been simplified, there are few CV inputs and the audio is output via PWM, but the RP2350 is fast enough that even a simple program can produce reasonably good sound.

Although there are no plans to use it as a VCO, it also supports V/oct.

Module description, Google translated:

Background
The 84th work of my own modular synth.
There are many suspicious circuit modules on sale on Aliexpress whose purpose is unknown.
Depending on your idea, you can easily create original modules at low cost.
This time, I planned to create a Pitch Shifter using such a suspicious and attractive Chinese module.

Pitch shifter
A pitch shifter is a type of effect that raises or lowers the frequency of the input sound. By layering 5th or octave sounds, you can create a thick sound.
There are also several Pitch shifter modules on the market for modular synths.

Specifications of the work
Eurorack standard 3U 8HP size
Power supply: 50mA (+12V), 10mA (-12V)

Pitch shifter module using BP1032 DSP IC manufactured by Mountain View Silicon, a Chinese semiconductor manufacturer.
The amount of pitch shift is fixed. In my case, I use it at a perfect fifth (5th).

DRY POT: Adjusts the DRY volume
WET POT: Adjusts the WET volume
INPUT LEVEL: Adjusts the input signal. Adjusts the input level to accommodate ±5V of modular synth sound and general line level.
OUTPUT LEVEL: Adjusts the output volume
Signal IN: Audio input
L Out: Left output. Not used with Pitch shift, but valid when the Reverb effect is selected.
R Out: Right output. Not used with Pitch shift, but valid when the Reverb effect is selected.
The biggest drawback of this module is that it does not have an interface for the applied effects or effect parameters on the front panel.
You can adjust the effects and parameters by connecting it to a PC via USB C.
In addition to being a pitch shifter, it can also be used as a reverb or delay depending on the settings.
ACPWorkbench
To switch effects, use PC software called ACPWorkbench.
This software is made in China and is of questionable origin, so use at your own risk. My PC's antivirus software did not detect any viruses, but I don't know if it's safe.
