Ring Modulated Generative Patch

YouTube via isotopeofme. via poictesme on the forum.
"Sunday morning generative patch with the VCO sine outputs ring modulating each other. Sounds a bit like I remember space mountain sounding! The lower part of the patch is one of the 2 oscillators being driven by the sample and hold, then heavily filtered to keep only the bass notes. The creschendo is the 24db VCF self oscillating thanks to a rising saw LFO on the secondary CV input."
Here's the patch:
Audio Signal Path
A110 Saw> 24db LPF
A110 Sine > RingMod Xin
24db LPF > main mix
A222 Sine > RingMod Yin
RingMod X*Y out > VCA
Noise > S&H Smp. in
VCA > MMF
MMF LP out > main mix

CV Path
LFO1 Square out > S&H Trig. in
LFO1 Sine > LFO2 CV
LFO2 Square out > ADSR Gate
ADSR > VCA
S&H out > VCO1 CV
LFO3 Tri out > MMF VCF Q CV
LFO3 SawUp out > 24db LPF QCV

ABBA's Minimoog

via Niklas of NEriks Audio

"The white Minimoog to the left in the picture belongs to Benny Andersson, ABBA. The picture was taken last time I had it in my workshop for service. Benny Andersson still owns the Minimoog but it currently resides in a studio in Stockholm called Roth-Händle."

BTW, you might recognize the name Roth Handle from these videos.

Baltimore SDIY Meeting #1 minutes for April 2008

via Logan on the AH list:
"Hello to all. The 1st meeting of the newly formed Baltimore SDIY (Synthesizer Do It Yourself) Group was held today at The Golden Corral Restaurant on Chesapeake Drive in Glen Burnie MD. Dave Vosh & I were the only attendees because of the short notice with which I put the meeting together. He brought his Doepfer A-100 Analog Modular System & I bought my DVC-1 Dual Voltage Controlled Oscillator module, DNG-1 Dual White/Pink Noise Generator module that I designed & built in 2005 & 2006 respectively, and a Single LFO module that I made on 11/06/1979 that still works. There are photos of Dave's system & my modules including photos of the two of us on my personal website.


We enjoyed checking out each other's systems and just talking about different approaches to the SDIY field as well as circuit pros & cons. This meeting really enhanced both of our viewpoints on this subject and may even lead to future live performances together. Today was an eye opener & an inspiration to the continuing construction on my own self-desgned & built analog music synthesizer.

In November of 2007 I decided that it was time to try & form an SDIY group here in Baltimore MD since some of the other groups seem to be located in the Upper East Coast, Midwest & West Coast areas, so due to the long distances & today's ever-increasing gas prices I find it difficult to attend any of these meetings. I really didn't know if anyone else would be interested in doing something like this when I put out my original Baltimore SDIY Group formation proposal on the AH & SDIY email groups lists last year.

Dave & I are hoping that there will be other members at the next meeting and we're also thinking about other locations to hold future SDIY meetings. The future meeting location(s) will hopefully be in an area that will be a central meeting place distance-wise since we all live in different parts of Maryland with one member living in Alexandria VA. We're also hoping to get other members to join the Baltimore SDIY Group who may not necessarily put together their own synthesizers but still have an interest in Electronic Music and/or music synthesizers. If you're interested in joining the Baltimore SDIY Group just send me an email to ProwlerRaven32 hotmail.com and request to be added to the group. Also include your contact phone number(s) if you feel comfortable doing so so that I will have a faster way to contact you in case the group has a pre-planned event with last minute changes that you may need to know about right away. Thanks for reading this posting and Happy SDIYing."

Roland SH-5

images via this auction
"The SH-5 is a classic yet very advanced monophonic synthesizer rivalled mainly by its successor, the SH-7. The SH-5 has just about two of everything. There are two analog VCOs with triangle, ramp, square and pulse waveforms, two LFO's, two filters, two VCA's, white and pink noise generators, and more. The oscillators can be modulated by the LFOs or the ADSR envelope generator. The two LFOs include controls for rate and waveshape: ramp, reverse ramp, triangle, sine, square, delay; and there is also a Sample + Hold feature. The two multi-mode filters include hi-pass, low-pass, and band-pass filtering with cutoff, resonance, keyboard tracking, envelope sensitivity (AR, ADSR or preset) and modulation (ramp, sine, square, s+h) controls plus an additional band-pass-only filter. The two VCAs offer Attack/Release and ADSR envelopes which can be triggered by the Sample + Hold, LFO #2 or an external audio trigger input. Extra features include the standard SH-type Mixer section with 5 sliders to adjust noise, VCO1, VCO2, ring mod and an external signal levels. Each of these 5 signals can be individually sent through the VCA, the multi-mode filter, the band-pass filter or both. The SH-5 even has stereo output with panning controls in the VCA section and portamento! The Ring Modulator alone is enough to wet your appetite for this synth. A serious analog mono-synth with lots of flexibility for creating serious electronic and dance music"

Roland System 100, 101 & 102 Keyboard & Expander

images via this auction
"The Synthesizer 101 section is a fully self-contained analog mono-synth. It features a 37-note keyboard (with no performance controls, velocity or aftertouch), and lots of sliders to tweak. Its design is similar to the SH-series analog synths. Controls for the VCO, LFO, VCF lowpass/highpass filters, VCA with ADSR, Noise, and Portamento/Glide effects are all within hands reach. There's also a handy A-440Hz tuning oscillator, like on the Minimoog. The Expander 102 section is a keyboard-less version of the 101, designed to stand upright and behind the main Synthesizer 101. More than one Expander 102 can be added to make your system fatter and fatter! The Expander is identical to the Synthesizer except that it replaces Portamento/Glide effects with a Sample-and-Hold feature for the LFO, the Noise gen. is replaced by a Ring Modulator, and the A-440 tuning osc. is replaced by weak/strong sync inputs and a mix-in jack. The Expander is an excellent way to add more oscillators and synth effects (the s&h and ring-mod) to a System 100. The oscillators can be synced if you have both modules. The 101 & 102 are already internally patched and ready to produce sounds, but that can be bypassed by external patching."

Update: box shot via this other auction from the same seller. There is also a System 100m 181 keyboard controller here.

Roland SBX-80 and TB-303

images via this auction

"The Roland TB-303 Bass Line is a synthesizer with built-in sequencer manufactured by the Roland corporation in 1982 and 1983 that had a defining role in the development of contemporary electronic music. The TB-303 (named for "Transistor Bass") was originally marketed to guitarists for bass accompaniment while practicing alone. Production lasted approximately 18 months, resulting in only 10,000 units. It was not until the mid- to late-1980s that DJs and electronic musicians in Chicago found a use for the machine in the context of the newly developing house music genre. At the time they were very cheap, which helped to contribute to their popularity. The TB-303 is considered a collector's item today, often valued at US $1000 to $3000. An example recently sold on eBay for US $2,275.00. Phuture's "Acid Tracks" is widely acknowledged to have been the first Acid House recording to incorporate prototypical TB-303 sounds. Earlier recordings featuring the TB-303 can be traced back as far as the early Electro scene, including artists such as Ice T, Newcleus, and Mantronix, as well as pop musicians such as Heaven 17 and Section 25. In the early 90's, as new Acid styles emerged, the 303 was often overdriven, producing a harsher sound. Examples of this technique include Hardfloor's 1992 EP "Acperience", and Interlect 3000's 1993 EP "Volcano". The well-known "acid" sound is typically produced by playing a repeating note pattern on the TB-303, while altering the filter's cutoff frequency, resonance, and envelope modulation. The TB-303's accent control modifies a note's volume, filter resonance, and envelope modulation, allowing further variations in timbre. A distortion effect, either by using a guitar effects pedal or overdriving the input of an audio mixer, is commonly used to give the TB-303 a denser, noisier timbre--as the resulting sound is much richer in harmonics. The head designer of the TB-303, Tadao Kikumoto, was also responsible for leading design of the TR-909 drum machine. " No details on the SBX-80. If you know more, feel free to comment. via ni hao in the comments of this post.

Update via burstgenerator in the comments: "the SBX-80 was good for syncing sequencing hardware to tape machines via SMPTE that it would then translate into midi-clock or roland sync, etc. link"

ID the Synth and Music

swissdoc sent in this mp3. Anyone know who composed the background music and what synth or synths are used?

Update via Z: "The 'bells' are Roland D-50, it's a preset, but I forgot which one. At 1:40, the narrator says "David Lanz" who is a new age composer that was on the Narada label back in the 80's. Not sure if he's the composer of the background music or not."
