Having some fun with Paul's new super easel & a small 12U buchla.
The MARF is really cool.
Working on some drones.
....
Really loving the 294 all over again. Such a under-rated module.
Some more pics of Paul's amazing easel.
A great drop from 1995.
The name “Barwang” means “place of water”. The winery is situated in the Hilltops region of New South Wales. The water source is a natural aquifer about 300m below the surface.

Am amazed at this wine's staying power. It's 21 years old. I wish I had a few more bottles left.
It's the last one I have from this case I think :-(

Korg PS 3200 - 9. Modulation Generator-1 (MG-1)
The MG-1 is basically an LFO.
It's quite central to modulation in the Korg PS 3200.
The voltages it produces is used for FM (frequency modulation) , FcM (cutoff frequency modulation) and AM (amplitude modulation) within the synth.
4 WAVEFORMS + pink & white noise.
The input on the left controls the frequency of the MG1
-5V to +5V
The MG is hardwired to the Signal Generators (SGs), the Filters & the VCA (Modulation Balance) sections.
That is, you don't need any patch cables to modulate these components.
When switched to the SGs you get FM.
When switched to the filters, you get cutoff frequency modulation (FcM)... called "Growl".
When switched to the Modulation Balance (VCA) section you get AM.... tremelo or ring modulation.
Looks like a good patch to try
The PS 3010 is useful but a synth such as a MS 20 should also produce interesting results.

216r - touch keyboard
Some pics taken during the building of a 216r ..
very similar to the 116
tHESE pics are just to help during trouble shooting.
Calibration is uber impt to get it working. !!!!

EMS Synthi - 2. Using the KS for the first time.
Some quick notes to help use the keyboard sequencer for the first time.
To use the sequencer patch D3 & A12 (as before), but place the pitch pin at I16
Turn the envelope shaper to sequencer.
Vertical range should be set to zero. (there is a switch at this position).
Set the Meter mode switch to CONTROL VOLTAGE.
The sequence length can be shortened or lengthened using this dial.

Korg PS 3200 - 7. Modulation Balance / Modulation VCA
There is just one knob & one input jack, but this section is very important, as it controls the balance between the modulation signals coming from the MG-1 and the S/H.
The balance between the MG-1 & S/H can be controlled manually with the knob.
However, it can also be controlled with CVs via the VCA control input jack.
Attack requires a CV between -5V and + 5V.
The MG-1 & S/H CVs are used alot in the PS 3200...such as applying FM to the signal generators.
MG-1 is used for effects like vibrato, and auto wow.
The S/H uses the MG-1 signal as the clock, and produces a stepped output CV for things such as random notes, and random cut-off frequency.
A trigger from the keyboard sets of the GEG (more about this patch later).

Korg PS 3200 - 6. Total Signal Modifiers (TSM)
This section comprises
1. Keyboard Volume Balance
2. Amplitude Modulation (AM)
3. Ensemble
4. VCA 1/Preset Volume
5. VCA 2/Preset Volume
1. Keyboard Volume Balance
This is what we perceive as BRIGHTNESS.
It's the difference in tone between the high and low range of the keyboard.... creates volume differences between different sections of the keyboard.
2. Amplitude Modulation (AM)
This adjusts the intensity of the amplitude modulation.
This is controlled by MG-1
It's how you produce effects like tremelo.
Level 5 = 100% modulation
Level 10 = 200% modulation (ring modulation??).
3. Ensemble
Creates the effect of many instruments playing together.
4. VCA 1/Preset Volume
Controls the volume as determined by the PRE VOL knob or and external CV signal
The position of the PRE VOL knob is stored in the preset memory.
The external CV signal must be 0 to +5V
5. VCA 2/Preset Volume
This is connected to the voltage processors, via the red internal patch switch.

Korg PS 3200 - 2. Signal Generators
There are 2 SGs per voice
The top 4 knobs are pretty standard waveform & octave selectors
The fine tune knob adjusts only SG2.
Speed & intensity are all about PWM .
Speed adjusts the frequency of the signal modulating the pulse width.
Intensity controls the sensitivity of modulation.
The pulse width of SG 1 & SG2 can be modulated by either MG-1 or the Sample & Hold
The MG-1 or S/H knob adjusts the sensitivity to modulation by the MG1 or the S/H,
Notice the two red switches on the bottom of this pic.
The one on the left, marked reverse, .... it reverses the phase of any external modulation signals.
The right switch, turns FM (from any external sources) on or off.
These lower switches, the two knobs & 6 jacks are for external modulation sources.
Not MG-1 or the S/H. More about this later.

Korg PS 3200 - 1. Intro
Some personal notes re the Korg PS 3200.
This synth was used on the soundtrack for the movie Nighthawks.
It's a good example of it's sounds. The artist was Keith Emerson.
This was the last synth Korg produced in the PS range. The previous being the 3100 & 3300.
It has 48 keys. Each key has it's own IC synthesizer circuit.... thus it's 48 voice polyphony.
That's 96 VCOs
But the biggest feature is the memory... 16 slots. ... Korg called this memory the "tone colours".
eACH of the 16 buttons is for a different "tone" or preset
To cancel a preset, just press the "cancel set " button.
To write a new set, press the write button, and one of the program selector buttons.
Make sure the memory protection switch is on most of the time, to prevent accidently erasing a preset.
Of course, to erase or add a new preset, the switch needs to be in the off position.
Memory is preserved when the synth is turned off.
There are two 1.5V AA (AM-3) batteries. Change these if the battery indicator lamp glows red.
tHE battery compartment is at the rear of the synth.
Just unscrew the panel. Make sure the synth is on, while changing the batteries, or you will loose your presets.
There are 32 knobs that can have their settings memorized.
This is quite a feat, when you consider the time .... 1978. The only other synth I can think of where you
can store the knob positions, is a Buchla 200e. ... and that's from 2005.
Not all the knobs positions can be memorized. Those that can are concentrated in the top left and are marked with yellow writing.
You can quickly override the memory by just pulling out any of the 32 control knobs for temporary readjustment.
To listen to the saved presets, make sure all the "32 programmable knobs" are pushed in.
Then, view each preset by pressing the 16 programming buttons.
To program a new preset:
1. program the sound with the 32 knobs pulled up.
2. When you are ready to save your preset flick the Memory Protect switch to off
Don't push the knobs in. (When you push a knob back in, it changes back to
the setting programmed into the memory).
3. Press the cancel set switch.
4. Press Write & one of the 16 tone buttons.
5. Flick memory protect back on.
The 3200 is made up of these components:
A. Signal Generators (SG)
B. Dynamic Lo-pass Filters (DLPF)
C. Envelope Modifier (EM)
D. Equalizer (EQ)
E. Total Signal Modifiers (TSM)
F. Modulation Balance / Modulation VCA
G. Sample & Hold (S/H)
H. Modulation Generator-1 (MG-1)
I. Modulation Generator-2 (MG-2)
J. General Envelope Generator (GEG)
K. Voltage Processors (VP)
L. Adding Amp
M. Volume outs (D vol,P vol,F vol).
N. Keyboard PS 3010
