"This rare Yamaha FM Synth sounds huge - basically 2 DX7's. Has the original DX1/5 Voice and Performance ROMS which are very rare to find these days. Has had a new battery fitted and new backlight (see new photos recently uploaded). Comes with flightcase and sustain pedal. New wooden side cheeks have been ordered and will be fitted when they arrive."

"Rare Crumar Orchestrator-2, a vintage Italian synthesizer. This analog synth is in working order but definitely needs to be serviced. There are obvious things like sliders being broken off, but it turns on and makes noise and the effects work. This was supposed to be a project and never got finished, so now it can be someone else's who will finally finish the job. If you are willing and excited to get your hands dirty (or just want to get some vintage gear affordably and pay someone to do it) then this is for you."

"Just a quick demo of my Maxikorg synth that I'm offering on EBAY."

Pics of the inside below. Also some scans of the manual.

"As for functionality, I have tested all of the knobs and sliders and everything seems to work with the following exceptions;

1. When the the Lower Voice wave shape knob is set to pulse wave and the Lower Voice "foot" control is in the 8' position, there is no sound from that oscillator. (The other oscillator on the lower voice still works).

2. The 3 position switch that controls the Upper Voice Vibrato is always on no matter what position the switch is in but the Vibrato sliders (Speed and Depth) still function normally.

Please note that you may find something else that is not quite right going on with this synth but considering it's age, I would say that over all it is functioning pretty well.

The synth has never been recapped and being almost 50 years old it is probably due for a complete capacitor change. This will undoubtedly fix the minor problems it currently has."

[$5] DIY eurorack modular synth Dual Slew Limiter


video upload by HAGIWO

"My 74th original eurorack modular synth DIY projects.
Dual Slew limiter , I aimed for simple functionality with few components.

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.

"Hi! Hope you're doing well. I'm back with a jam and this time I have the Cirkon 2 doing most of the sequencing. I received the Cirklon sometime last year after a 4+ year wait but couldn't find the time to fully dive into it. Reviving an old composition (3 mother-32's at the time) and adding a few more voices seemed an exciting way to kick the tires on the Cirklon and revise the original piece. Both the Cirklon and Digitakt are running in their song modes, respectively. Everything is sequenced from the Cirklon, except the Digitakt. I've strayed into musical territory that I usually shy away from (and don't fully understand) but I enjoyed it nonetheless and I hope you enjoying listening too."
