Plan B Model 17 Triple Event Timer: the one nobody "got"

An Interview with Barry Schrader

Hi everyone! As you know Barry Schrader will be giving his farewell concert at CalArts on September 26. The following is the beginning of my interview with him. I opted to post the questions and answers as they come in.  New QAs will get a new post so you do not miss them and they will be added to this post so we have one central post for the full interview. This should make it easier for all of us to consume in our busy lives, and it will allow you to send in any questions that may come to mind during the interview process.  If you have anything you'd like to ask Barry, feel free to send it in to matrixsynth@gmail.com.  This is a rare opportunity for us to get insight on a significant bit of synthesizer history, specifically with early Buchla systems, and I'd like to thank Barry for this opportunity. Thank you Barry!

Rare PLAN B MILTON Sequencer in Serge Format

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

via this auction

"Serge format 4 rows of 16 voltage steps, 2 rows of trigger steps
Includes standard rack ears (4U tall) and a Blacet external power supply (120v can be switched to 240v).

No menus or complex key commands!

There were several of these built around 10 years ago. Talking to people some assume they've owned, seen or heard stories about this specific unit. After further asking they tend to NOT have realized there were several made, even some in different formats like Modcan or Wiard. Still this is a very rare model that does not come up for sale on a regular basis.

Can also be run off a MOTM supply, uses a standard +15v, -15v DC.
I'm including a detachable ground cable and detachable banana clip with 2 leads.
The strategy is the sequencer is grounded to the PSU then the PSU is grounded via a lead to other racks/boats/PSUs to share a common ground which is necessary with banana systems and quite simple.

This sequencer has a powerful voltage addressing of sequencer steps feature as an alternate to the traditional gate/trig input advances a stage which is also available.
A voltage value, even from a keyboard 1v/oct can optionally be sent to the sequencer to choose a step based on voltage level.

A trigger can optionally be sent to only sample an incoming voltage value at that time rather than continuously change steps as the voltage changes.

Please note you you would use an external quantitizer, clock, slew or router switch module to achieve those functions. The Milton provides a banana for a gate out per step in order to trigger external events on a specific step patched into.

Basically, while not built as a Buchla sequencer, the voltage is not quantitized and should be useful unless something very specific and Buchla is required like a gate/trigger combo or addressing steps in a specific way without scaling. Then again there are more and more specialized tools to connect Serge and Euro to Buchla.

Conversely one could directly park this over another non-Serge Banana system, connect the ground and be in business. If one wants to connect this to Euro or 5U you will need some kind of jack conversion adapter and ground tie but the voltages should be fine

While not overly complex, just a general advisory that you will need a basic understanding of modulars to use it and interfacing cross system if you have something not Banana based. Please look up the general strategies to interface say software, MIDI or drum machines to an analog sequencer. They should work with this sequencer."

2 Racks

The A-119 has been modded with a quieter TL064 opamp for better signal to noise. Condor linear power supply has enough power for quite a few more modules. Original and rare PlanB modules are really cool and difficult to find nowadays (the lowpass gate is a personal favorite). Everything works perfectly. An analog beast!"

Rare Plan B Model 10 Polyphonic Envelope Eurorack Module

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

via this auction

"This seems to be also one of the "older" modules from the series. It works fine without any issue.

Reason why the module is called “polyphonic” is because it can output 4 different type of voltage “envelope” at the same time.

More info about this module here and here"

"The PlanB model 10 is a multifunctional module, not only a simple envelope.
The name “polyphonic envelope” does not describe the functions of this great module, the reason why they called it “polyphonic” is because it can output 4 different type of voltage “envelope” at the same time.
In fact the M10 is way more versatile than an envelope, this is really similar to the Bananalogue VCS module, a multitask voltage controlled cv generator .

The main task is the ENVELOPE.
The envelope consist of an AD env with RISE (0.5 ms-5 min attack)and FALL (0.5 ms – 5 min decay/release) controlled not by gate signals but by Triggers.
The attack and decay time can stretched x8 times their duration with the TIMEBASE control knob (so the complete envelope can last from 0.5 milliseconds to 20 minutes).
You can stretch the time manually just turning the knob or controlling it with the VC TB (voltage control timebase).
The VC TB can act in positive or negative, so it can add or subtract.
Than there is the level of the env, which is bipolar too , so it can act as a positive or inverted envelope.
On the left there are the 5 connectors for the 4 different envelopes generated:

EOC
EOA
RAMP
2x AD (with ad contour switch)
The AD acts as the classic “trig” envelope, with 3 different contour (log, lin, exp).
The RAMP is a ramp with rise time 2x the RISE control time.
The EOA is a sustained square which falls when receive a trig and performs the AD cycle at the “End Of Attack”.
The EOC acts as the EOA but the AD starts at the End Of Contour.

LFO MODE

The rise-fall cycle can be looped and can also work as an lfo.
Using the rise and fall it can produce various waveform between the tri, square, saw, ramp…
The interesting thing is that the timebase knob can control the time of the lfo, so it a vc lfo, the other thing that can lead to creative results is the fact that the rate of the lfo is not controlled by the timebase only, but it ’s a mix of the rise and fall time.
So the shorter is the R&F the faster will be the lfo rate.

VCO MODE

The third interesting mode is the vco function.
The module has a triangle-core , so it can sound useful even as a vco.
To get the vco mode you have to switch into LFO and use fast R&F time and “tune” the oscillator with the timebase function and VC TB to control it with a keyboard cv.
It does not reach very high frequencies but can be used on the low and mid range as an audio modulator or a audio source.

TIPS:
I noticed two useful tips:

As the core is a TRI-core the envelope create a sort of clip when, reached the max value,start the fall.
To avoid the clip it’s useful to use a lowpass filter post the VCA.
In LFO mode don’t connect any source to the trig in because the summing of the two sources can damage the module , too high voltage!"

http://felixinferious.blogspot.com/

Addendum from Peter @ Plan B:

Regarding the separate START/STOP inputs:
Doing it with two inputs instead of one is a flashback from my Buchla days. My feeling it's better this way as you can if you wish use separate signals to start and stop the counting. This way you could for instance use a keyboard trigger to start it, which would also be used to start a sequencer and reset that seq to stage 1. Then you could use the gate output of let's say stage eight of that sequencer to stop the M28. This way you can get repeated eight beat phrases from the 28 which would begin on the depression of a keyboard. It would be much harder to do that with a single start/stop input.
