Description (Google translated):
The 75th work of my own modular synth. One of the most basic modules of a modular synth is the Slew Limiter. Eurorack's most popular module, Make noise Maths, also has this slew limiter function.
I have also created modules with Slew limter functionality, but since I have never created a Slew limiter itself, I decided to create one.
Product specifications Eurorack standard 3U 6HP size Power supply: 15mA (+12V), 15mA (-12V)
Dual Slew Limiter with two types of functions. Priority is given to low price and fewer parts.
top of module Slew Limiter allows you to select the slew rate range from three types. Select 3 types of range with the toggle switch. L range: Assumed to be used for slow CV such as LFO M range: Assuming the use of pitch CV portamento S range: Assumes the use of an audio frequency low-pass filter Control the slew rate with Pot.
Supports bipolar input. Since the accuracy of the output voltage with respect to the input voltage is high, it can be used for V/oct pitch CV.
module bottom Slew Limiter allows you to set Rise and Fall slew rates individually. It is assumed that ASR envelope generator will be used.
Supports bipolar input. Due to the circuit, the accuracy of the output voltage with respect to the input voltage is low. The use of V/oct pitch CV is not assumed.
"This sample drum module was made with Seeeduino Xiao which processes wav data converted to binary as a sample program that is saved to internal memory, in my scheme I did not attach a trigger switch and bipolar voltage safety because I only used one 9 volt power supply. you can download the schema and the ino program that I'm already using on my google drive . Link : https://drive.google.com/file/d/1vAIV... . Caution use a trigger below 3 volts otherwise you will damage it .

":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.

According to the creator of these controllers, Craigyb:
"So when I was 16 (around 45 years ago) I used to dream of the Arp Quadra. A friend of mine who wasn't a keyboard player, but just wealthy bought one and it was sat in his front room doing nothing unless I could call around after school and have a play on this great synth.
Now I know I could probably afford to buy one, but the wife would kill me quicker than the Russians, so instead I took Cherry Audio's VST of the Quadra and created a physical beast with a PC built in to create sounds.
I then followed that up with a synth that I've never met in real life AFAIK but is also quite legendary, the Elka Synth (again a VST emulation by Cherry Audio).
I'm currently working on the Memory Moog version (MemoryMode by Cherry Audio) and I just need to finish the actual hardware as the software controller is complete."

"This module is an open source general-purpose CV/Gate module based on Arduino nano.
It can be applied to various CV/Gate modules by changing the program.
There are some performance limitations, but it uses general-purpose inexpensive components.
Square VCO:
Audio output operation is somewhat unstable and produces a noise sound.
Square wave oscillator with V/oct support.
LFO for vibrato and octave like chiptune.
The capacitor in the D11 output circuit needs to be removed."

background The 78th work of my own modular synth. One of Eurorack's standard modules is MATHS. One of the uses of MATHS is Envelope follower, but this Envelope follower is difficult to use properly. I have created an Envelope follower in the past. This time, I decided to create a compressor as one of the application examples of Envelope follower.
Opto compressor Compressors include VCA and FET as means of compressing audio, but there is also a type called opto compressor that uses Vactrol (analog photocoupler). Although the responsiveness is poor, we decided to create an opto compressor this time because it can be created inexpensively with few parts.
Product specifications Eurorack standard 3U 6HP size Power supply: 20mA (+12V), 20mA (-12V)
opto compressor using Vactrol LCR-0203. The idea is to use it to increase the sound pressure by compressing the entire MIXed audio, or to change the impression of the sound by compressing a single percussion sound such as KICK.
THRESHOLD: Adjustment of the level at which compression starts. RATIO: Attenuation rate adjustment. By increasing RATIO, it is possible to compress at a magnification of 1x or less. In other words, the louder the input audio, the lower the output can be. RELEASE: Adjust the RELEASE TIME of the built-in Envelope follower. VOLUME: Audio out amplification. Lowering the THRESHOLD lowers the overall volume, so the VOLUME POT compensates for the volume drop. LED: The more compresson is applied, the brighter the light will light up. Also used for calibration. IN: Audio input. It is assumed to be used at Vpp=10V (-5V~+5V). OUT: Audio out
Production cost Total about $9 --------------------------------- LCR-0203 $1 Front panel $1 Envelope follower module $2 Variable resistance $0.3*4pcs Others (see link below for general purpose parts)

BP1032 DSP Reverb module from China based FX module.
Effect types and parameters can be changed using PC software called APCWrokbench.
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.
