Powertran Transcendent 2000


YouTube via telecastersteve | March 05, 2009 |

"2nd youtube video of Transcendent 2000, all the parts were played on this synth using SONAR and a digital delay..no other synths used!"

via this auction
"Wave Shapes - Pulse / Saw / Triangle / Noise
1 Oscillator / Sub Oscillator
1 Filter - LPF / BPF / Self-Reso 2 Pole
2 Envelope Generators - ADSR / AD
Midi Control via CV Gate
37 keys

Some things you may not know about this surprising synth –
1. The ADSR envelope generator can be set to repeat mode, turning the envelopes into a
second (low-range) LFO.
2. The ADSR envelope generator can be bypassed, allowing the oscillator to sound indefinitely, perfect for drones, wind noises etc.
3. The triangle Wave Shape is adjustable from a ramp to a sawtooth allowing some rather subtle, delicate timbres to be created.
4. There is also VCF input that takes the supplied expression pedal, allowing the filter’s cutoff to be played like a wah-wah. Talking of which, the filter can self-resonate with the best of them and can be switched between BP and LP modes."

Roberson Audio RA Mowg, Oddy-Free and Prophanity



via Roberson Audio

"RA Mowg

The Roberson Audio Synthesizers interpretation of the MiniMoog Model D synthesizer."

From the ReadMe file:
“This synth is meant to be a model of the Minimoog Model D synthesizer, and a lot of time was invested to get it the way it sounds, including oscillator and filter character as well as modulation struction and response.

A few notes to keep in mind before you get to playing with it:
-The synth was built with 48khz sample rate in mind, so it may not sound the same in other sample rates (generally though, higher will not have negative effects)

-Even though a mod wheel is not present in the graphical portion of the synth, using the mod wheel on your keyboard still has the same effect as the real synth

-There is a switch on the synth for an external input. In a real Minimoog, this could receive any audio input, but for this plug-in it has been hardwired as a feedback loop from the audio output of the synth. Be careful pushing the volume of it too high!

-The synth is completely monophonic, with priority given to last note played. Realism has been sacrificed for playability, but I believe it is a good trade-off in this instance.

-Update Version 1.2 *IMPORTANT*

-Made a few modifications, basic playability is largely unchanged. Most mods came in the form of filter modifications, it is BIG sounding now. Also, can resonate itself into oblivion, which itself can be dependent on what sample rate you are using, so BE CAREFUL. You’ve been warned. Some patches from prior versions may then have problems or may cause unwanted side-effects, so load them with caution.

Any updates will be reflected in this document with the corresponding update packs. If you have any questions or comments about the synth, you may refer them to blu_gruv@lycos.com, or contact me on KVR Audio under the screen name “Chris Roberson”.

Artwork for the instrument was provided by Modeler of KVR Audio forums. Truly brilliant work if I do say so myself.

I hope you enjoy using the synth, and look forward to hearing what you have to say about it.

Cheers,

From the Readme file:

'The absolutely fantastic artwork and GUI were done by androidlove and Modeler of KVR, many many
thanks to him as the synth just wouldn’t be the same without it.

Now onto business…

The Oddy-Free is quite apparently a emu of an Arp Odyssey Mk.II, and much attention
to detail was given in the layout of the signal path to have it behave as accurately
as possible. Granted it does have just a touch more umph than most originals would,
this particular emulation was based on the “illegal” filter versions based on Moog’s
-24dB Low-Pass filter, so it sounds quite a bit smoother and richer but at the same
it can produce the harsh metallic tones known from the Odyssey.

I really hope you enjoy the synth, I know that I enjoyed making it. It brings me joy to
release free models of synth emulations that otherwise one may have to pay out the nose
to get.

If you liked the synth and/or were able to find good use of it, please vote for me
and it as the number one entry in the KVR Developer Competition ’07.
——————————————————————————————

Update Version 1.1
Changes:
–new face panel, a little bit of a more realistic touch.
–fixed spelling issues on face panel
–fixed masking problem with slider cap graphics, so there is no longer the black box
around the caps (rather nice fix)
–added “analog” features, including oscillator and filter instability, along with a few
minor affects on related components, also a very subtle power supply bleed-over to
related components.
–added a slight filtering to the final output to reduce the unrealistic high end of the Oddy
just a slight amount for accuracy purposes.
–added voltage and amplification mods to waveforms to enhance edginess of waveforms
and certain modulations (you may need to correct previously made patches.)
–added user-made patch banks and individual FXP files for the Oddy, hopefully you’ll enjoy. :)
–and probably some other things I forgot at 2 in the morning. :D

Updated Version 1.2
Changes:
–numerous internal changes to oscillator structure, including totally different oscillators to begin with
–modified filter to behave differently and a little more “analog”.
–removed much pre-EQ in the signal path, making it a much easier to mix instrument
–removed older user patch banks from pack, they became incompatible with new oscillators and filter.”

-Update Version 1.4 *IMPORTANT*

-Made a few modifications, basic playability is largely unchanged. Most mods came in the form of filter modifications, it is BIG sounding now. Also, can resonate itself into oblivion, which itself can be dependent on what sample rate you are using, so BE CAREFUL. You’ve been warned. Some patches from prior versions may then have problems or may cause unwanted side-effects, so load them with caution.

From the ReadMe file:

“Hi and thanks for downloading Prophanity, the Prophet 5 clone.

I know it’s been a long time coming, so I hope you enjoy.

There isn’t a terrible lot to say for the synth, it’s a model of the Sequential Circuits Prophet 5. Much time was given for attention to detail in nearly every aspect of the instrument, and most every subtlety has been accounted for.

The excellent artwork was done courtesy of Modeler of KVR audio.

If you have any comments or requests or problems/questions with the synth, my email is blu_gruv@lycos.com, and can also be found at www.myspace.com/mrblugruv.

Hope you enjoy the synth.

UPDATE VERSION 1.1:

-Added unison mode

-implemented new oscillators, which behave more accurately in poly-mod section

-modified filter design to sound more pleasing

-changed envelope response to exponential, no more linear envelopes

-added per-voice instability, to simulate the multiple signal path architecture of the original

UPDATE VERSION 1.2:

-fixed some oscillator distortion problems

-massively overhauled filter/preEQ to make it more pleasing and technically correct

-many small adjustments to hone behavior to that which is closer to original

-Update Version 1.4 *IMPORTANT*

-Made a few modifications, basic playability is largely unchanged. Most mods came in the form of filter modifications, it is BIG sounding now. Also, can resonate itself into oblivion, which itself can be dependent on what sample rate you are using, so BE CAREFUL. You’ve been warned. Some patches from prior versions may then have problems or may cause unwanted side-effects, so load them with caution.”

The end result of all this is a (hopefully) more true-to-life representation of the original. As mentioned above, direct any questions to blu_gruv@lycos.com, www.myspace.com/mrblugruv, or find me on KVR under the user name “Chris Roberson”.

Sincerely,
Chris Roberson."

COMDYNA LGP-20 Analog Computing System

via this auction
As always, the seller's description:
"This machine is a combination of two Comdyna GP-10 analog computers and a MicroHybrid I digital control and interface system. It is one of only 20 made for the US Navy for use in their control laboratory schools. It offers 20 Operational Amplifiers, multipliers, coefficient setting pots, etc etc. The MicroHybrid has comparators, two counters, and I/O facilities for controlling the two GP-10 machines. The Operator's and Maintenance Manual, as well as various descriptive brochures, are included. It is assumed you have a basic familiarity with analog computation techniques, and the proper math backround to be able to set up the programming.

I purchased this machine some years ago for use in experimental music synthesis and composing. It was to be an expansion of my Comdyna GP-6 machine (which I am using currently). It was purchased in the condition shown and described below. My music research has branched out into other channels, so this Computer is not going to be used for the original purpose. Time to get it out of storage in into use!

This LGP-20 apparently had it's control panel broken at some point in it's life, and another LGP panel was provided. The replacement panel was cut out of a machine, and has a power transformer and the external sockets, as well as a connector for the regulator board attached. These parts are also on the main machine. The control panel harness must be spliced into the existing wiring. The main machine harness has bits and pieces of the switches, etc still attached. The clean-up and splicing job should take about an hour for a competent tech to perform.

The Power Supply regulator board is missing. There are three main options:
1. If one is still available from Comdyna, purchase it. Even a 'blank' board can then be easily populated.
2. Make a new board. All parts are common and are instantly available from Mouser, Digikey, etc,. The complete schematics and layout is in the Manual.
3. Operate the System using external power supplies - plus/minus 15VDC, plus/minus 10VDC (well regulated) and plus 5VDC for the MicroHybrid is required. Current is an amp or two, and there are many supplies which will do the job.

I have recently powered up the MicroHybrid portion of the System and it appears to be working as it should.

If you are experienced in basic electronic-technician level work, or can enlist the services of someone who is, restoring this machine will be easy. I just have too many other projects currently to allow the luxury of time needed for it." This one in via Brian Kehew.

Update via dkelvey in the comments: I have a LGP-20 that is working. I just this last weekend had it doing spyrogrphs at the Maker Fair in San Mateo, CA. I can assist in connecting the wires by giving someone a point to point listing. I'd be most interested in a copy of the LGP-20 manual though. That I don't have.
