Harmonic Transformer Plus

video upload by Randy Piscione

"In this video, I demonstrate the extenders for the Harmonic Transformer Eurorack module from PM Foundations. Each harmonic PCB has an SSI2131 VCO to generate the sine wave. Since this is a full-featured, very stable VCO, PM Foundations designed an easy to populate daughter card that would bring out the other functions."

Follow-up to this post.

"This is a demo of the PM Foundations Harmonic Transformer Eurorack Module. Couple of things - when I listed the harmonics I used, I listed 11. Oops. I also mentioned the module running through an EG and a VCA, which is of course not correct.

Harmonic Transformer Initial Fooling Around video upload by Randy Piscione

"PM Foundations Harmonic Transformer - Initial bit of fooling around with the independent characteristics of each harmonic. In this case, some of the harmonics fade in gradually, with various speeds and amounts of pitch modulation. The module can produce some interesting sounds that seem like acoustic instruments, maybe from another planet."

Harmonic Transformer Clarinet Test

video upload by Randy Piscione

"PM Foundations Harmonic Transformer - this video is a very initial test of reproducing the timbre of a real instrument, in this case a clarinet. I didn't spend any time on the envelope, only the timbre, and the playing is certainly rough. A full demo will follow shortly.

This was the video I used as a comparison:"

1980 Dual Manual Prophet 10 Dual Mode

video upload by Randy Piscione

"Dual mode on the 1980 Prophet 10 couples the keyboards (behind the scenes), so either keyboard will play both internal Prophet 5s. In this video, I’ve combined mostly similar but not identical sounds to get a better representation of an actual instrument or combination of instruments. The synth has a fairly simple subtractive voice, so consider any sound I mention to have an assumed “-ish” at the end. The songs I’ve chosen are also representative, certainly not exact. All patches are mine. I hope you’ll consider watching the entire video and apologize for any ads you might need to endure. My videos are not monetized by me.

0:00 Starts with a sawtooth-based string patch, then layered with a pulse-based string patch. I think this one worked well.
1:05 Starts with a basic woodwind patch, then layered with a woodwind ensemble patch.
2:08 Starts with another sawtooth-based string patch, then layered with an orchestra patch.
3:43 Starts with a brass patch, then layered with a bigger brass patch."

Nonlinearcircuits VCO Demo

video upload by Randy Piscione

"This is a demo of an older Nonlinearcircuits VCO, based on a Mikulic/Electronotes core with phase sync and pan-pulse circuitry from the Aries AR-338.

The video starts with a sequence, and scope shots of four of the five waveforms the VCO puts out. I didn’t bother with the triangle, but there is a pulse, then saw, then pan pulse and processed saw. These are eventually blended together, and then the left side VCO is faded in. This one is hard synced to another VCO. The equipment list is at the bottom of the description.

The PCB is not designed for Eurorack so I built a dual version to fit them behind a double panel. I originally built it in 2015, made a new panel in 2018, and it stopped working shortly after that. Each VCO required 50 hookups, so 100 wires, 200 solder joints. Ouch!

When it failed, for no apparent reason, I removed all of the point-to-point wiring, couldn’t figure out what happened, and put it aside for quite a few years. If only I had known then what I know now, the failure was a simple IC problem. I had purchased TL074s from eBay that turned out to be pirate versions. It would’ve been a one minute fix. I decided to tackle it again recently, and re-soldered all of the wires. Unfortunately, I used crap wire, so off those came, and I did it again! Still had some issues but with substantial help from John at PM Foundations, we were able to bring it back to life.

Vintage Dual Manual Sequential Prophet 10 Demo 2

video upload by Randy Piscione

"Another demo, this time a bit more involved. Patches are my own, playing is a little rough as usual, all sounds are from the Prophet except the drums. Actual tunes are not lifts, just for demo purposes. I also tried to duplicate a pair of famous bass sounds.

0:00 Chameleon
1:49 Bells jam
2:55 Birdland - I did this one for the FVS demo, figured I'd see how it turns out on the Prophet. This was interesting, I think the bass is better on the Prophet but the FVS certainly does nice chords.
3:48 Blues jam - two slightly different organ patches, using Double mode to combine them.
5:57 Nice to nuts - for the last 6 minutes, I played the controls live on both manuals, ending up with spaceships, machines, room tones and whatever else comes out of two Prophets."

First quick Vintage Sequential Prophet 10 Demo

video upload by Randy Piscione

"I have traded the Oberheim FVS for a Vintage Sequential Dual Manual Prophet 10. As cool as the Oberheim is, and as much as I loved the sound, the P10 is much more of a player's instrument. This is just a quick first bit of noodling, both patches are mine."

FVS vs reSEMble Nov 2023

video upload by Randy Piscione

"Another demo of the PM Foundations reSEMble, four of them (https://www.tindie.com/stores/pmfound....) This time, I've duplicated a patch on the FVS and the reSEMbles. I was going to do a dry video but figured I'd do a little tune. At the beginning you can see my left hand playing the FVS while the right hand plays the reSEMbles, and since they alternate for a brief time, you can compare the two instruments. Together they sound amazing! I imagine this is what it's like to play a dual manual eight voice. There are also some ARPs, a Rhodes, a Kurzweil K2600XS, and an Alesis SR16 adding support."

PM Foundations FVS Plus Separates

video upload by Randy Piscione

"More PM Foundations (https://www.tindie.com/stores/pmfound...) multi-reSEMble panel comping. Everything except drums is coming from the cabinet with the reSEMbles and separates in it. The bass is coming from the separates (the SEM-based modules). The drums are an Alesis SR-16. I made most if not all of these modules.

You can get a closer look at the separates here: [posted here]

and the SEM tribute panels (reSEMBLE) here: [posted here]"

PMF SEM Tribute Modules

Demo video upload by Randy Piscione

"Demo of a DIY modular SEM, sort of. There is some talking at the beginning (GASP!). PCBs and panels are available here: https://www.tindie.com/stores/pmfound.... The 'Oberheim Tribute' modules are also used in the reSEMble panel. The VCF has been built with the option to self-resonate but can also be built to emulate the SEM’s behaviour. All sounds except drums are from the PM Foundations modules. The drums are from a Mutable Instruments Anushri. This is not an opus, just some sounds. The modules can duplicate the sounds of an SEM but I wanted to show some of the extra bits."

reSEMble FVS Poly Demo

video upload by Randy Piscione

"Another demo of four reSEMble panels (https://www.tindie.com/products/pmfou..., this time polyphonic. Also included the Oberheim FVS in this one. I'd like to encourage everyone to listen to the entire video, in stereo, with headphones if possible.

Before anyone says anything silly like, 'it doesn't sound like the FVS,' you are correct. Why is that? Although this can sound very similar to an FVS, it takes time to get the patch exact, I wanted to demo the PM Foundations version of an FVS, and even an FVS doesn't sound like an FVS, meaning none of my four SEMs sound exactly the same. The VCOs, VCF and EGs are based on the SEM. If you want to hear how close reSEMble can get to an SEM, check out my other videos.

I have included the wavefolders and ring modulators in some of the patches as well."

Resemble FVS Mono

video upload by Randy Piscione

"First, very quick, demo of a four-voice reSEMble, four PM Foundations reSEMble panels in monophonic mode. What if an SEM had three VCOs instead of two? That's twelve VCOs! What if, maybe halfway through fooling with these, you mixed in four wavefolders? The four panels are panned in stereo, listen loud if you can. https://www.tindie.com/products/pmfou..."

Synth Brochures from Randy Piscione's Archives

"Midiverse - TV recently posted a video of vintage synth ads, which I noticed on Matrixsynth [posted here]. This got me thinking about my own archives, mostly from the 1970s and early 80s, so here's a not as slick as theirs slideshow of my stuff. Music includes an Anushri, FVS, some ARPs and a K2600XS."

You may notice some of the modules moving a bit when I patch them. The rails I used for this case were more shallow than all of the other rails I have ever purchased, so my screws are a bit too long. I'm waiting for some washers to arrive to remedy this."

Oberheim ARP Noodle

video upload by Randy Piscione

"Quick noodle with some vintage bits, cell phone video and audio. A bit showy, and a bit rough in places. Volume is low too, and the "mix" is at the whims of my phone mic. Oberheim FVS on bass, ARP Odyssey, Axxe and Little Brother on lead, a bit of Alesis SR-16 on drums. Since my right wrist still has a non-union, doing this is challenging but getting through a minute or so is still possible."
