E-Mu Morpheus Z-Plane Synthesizer Tutorial | VHS (1994)

Daniel Johnson

"This video captures a rare VHS-era intro to the E-Mu Morpheus and Z-Plane Synthesis.

Synthesist Gerry Bassermann discusses the Morpheus hardware and then digs into creating sounds with it.

The Z-Plane Filter, introduced with the Morpheus, lets you control the characteristics of the filter precisely, including frequency, bandwidth and degree of peak. This lets you get a wide variety of filter effects and also lets you morph between filter settings"

1975 ROLAND RS-101 - Vintage Polyphonic Analog String Machine

"Stunning 1975 Roland RS-101 String Machine in fully serviced and restored condition.

Fully polyphonic string synth with individual VCAs and envelopes for each note.

The first of the Roland synths to feature the lush Ensemble effect (the RS-101 has 4 modulated delay lines vs the rs202's 3 delays and the difference shows) and this stringer has the mojo in spades. It's as lush as they come.
The excellent feeling 5-octave Keyboard is split, bi-timbral, with Strings I, Strings II, and Brass either side of the split, and with variable tone control, fully independent Slow Attack, Variable Sustain, and Volume Soft options.

Very expressive synth, with a beautiful haunting tone, and being fully polyphonic (unlike the earlier Solina) the expressivity is fantastic. Sits perfectly in a mix. Again, the ensemble

This synth has undergone meticulous restoration, including recapping of almost 100 caps, full restoration of all pots, switches, etc. Keybed fully restored. It's bulletproof and should provide use for many more decades to come.

230v model."

Waldorf Microwave 1 Rev.A 2.0os w/ Stereoping Controller & Extras

Note: Auction links are affiliate links for which the site may be compensated.

via this auction

"Waldorf Microwave 1 in the most sought after Revision A. It has been upgraded this year to the version 2.0 Operating system.

It works great and sounds amazing. It's been babied and used in a clean, climate controlled studio. It stays dust free and is always covered when not in use. It's 220v so you'll need a step up transformer in the USA, I recommend Acupwr for safety and reliability.

Comes with the Stereoping synth controller that really opens up your ability to tweak in real time and make your own patches. Along with are the two factory patch cards, Claudis Bruse and Dave Gould Techno card, plus two more 256k memory cards to back up your patches as well as three other Korg Mega Rams with 4 banks per card (these are all really rare). In addition to this are a set of factory and other manuals that I’ve collected over the years. I will also throw in the two right angle midi cables that work great for attaching the Stereoping to the MW. I have never seen such a kit of Microwave items in one listing, here's a chance to own a rare and amazing machine."

Beast-Tek Double Dragon Dual LFO and Ramp Generator

Beast-Tek

2nd video in playlist: "Double Dragon Dual LFO channel 1 in ramp mode controlling a VCA with channel 2 at audio rate"

via Beast-Tek

"Double Dragon
​
Double Dragon is a dual complex LFO that packs a fatal punch! The second LFO can be twisted, warped, destroyed and modulated by the first LFO using one of seven different algorithms to produce modulations more wild than a spinning round house kick to the face!

The amount of algorithm based modulation can be blended from zero all the way to full depth using the MOD control and CV input. Each algorithm has a parameter to tweak the modulation, again with full CV control.

The glowing "Dragon Eye" provides visual feedback of the selected mode at all times.

Double Dragon has 3 different frequency or "speed" ranges accessible by the press of the encoder - allowing Double Dragon to go all the way from prehistoric times with a cycle rate of approx. 2.5 hours for one cycle to drone territory and beyond at 1.28 khz.

If this wasn't enough functionality already, configuration jumpers on the back allow each of the two LFOs to be switched from bipolar LFO mode to RAMP mode to generate unipolar ramp signals. From "ramp down" through "triangle" all the way to "ramp up" to control a VCA or modulate using an positive-only envelope. Two additional jumpers allow the RESET input to be repurposed to 1-Shot mode (one complete Wave or Ramp cycle per trigger input) or hang mode (output is held or "paused" while the input is high) providing maximum flexibility.

Want to put your modulation on hold during a fill, quite section or certain measure? - just switch the Dragon into hang mode and all your problems are solved.

Placing LFO 1 into both RAMP and 1-Shot mode in combination with a VCA module allows Double Dragon to become a drum voice - with LFO 1 providing the envelope and LFO 2 providing the audio signal. Even in RAMP mode, LFO 1 still modulates LFO 2 so the envelope produced by LFO 1 can still modulate LFO."

elta music pm-02 exploration

impurfekt

"the elta music pm-02 is a eurorack version of the recent polyvox-m desktop unit. it is a simplified version of the original polyvoks synthesizer; possessing similar oscillator and filter circuitry.

this synth is my first in-person exposure to the polyvoks family. it certainly lives up to its reputation. the oscillators are raw and dirty (though cleaner when patched out to other modules). the filter is dirty and has the most violent resonance i've ever heard. the envelope is nice and snappy. the unit is gorgeous and built like a tank. it has enough jacks to easily incorporate other modules.

while i enjoyed using the pm-02 i found the filter lacking in musicality. it's generally rough and dirty (not a bad thing); and adding resonance just makes it louder and dirtier. i was pleased by the saw and square oscillators. the square can sound nice and woody. to me the triangle oscillator sounds more like a muted saw than a triangle. i struggled to create bell-like tones for example.

due to the general character of the filter i've decided to look at other options; but if you like the tone of this synth it's an excellent choice. it's well built and excels at hard, sharp, dirty, nasty sounds.

filter sweeps (low pass) at 0:15
filter sweeps (band pass) at 5:26
saw arp at 8:48
bass line at 12:02
triangle arp at 16:11
band pass lead at 21:08

Analog synth vibrato with hand movement

GS Music

"We connected an accelerometer to the pitch CV input on the new GS Apollo synthesizer and this is what we got.
The accelerometer module was slightly modified. Some filters were added in order to achieve a better response.
No modulation wheel or aftertouch was used."
