The αρπ Filter (alpha-rho-pi) of NLC sounds great. .... very much like the diode ladder used in the Roland TB 303
It's actually a hybrid/variation of the vintage Electronotes and ARP designs.
Hard to describe it's sound ... inorganic, man-made (in a good way).
The filter design has 2 audio inputs, two CV modulation ins and two audio outs (Bandpass & LP).
I'm not aware of NLC's producing a Eurorack version of this great module. So for now, if you want one
you'll have to build athe 4U banana-fied panel .... it's well worth it.

As you can seen from the pics I'm using just the BP out & one in & one CV mod in.
The CV is being modulated from a jerkoff.
This is a old video using the αρπ Filter:

Kilpatrick Phenol & NLC Divine CMOS
This circuit uses some good old CMOS 4000 chips. To be specific they are 4070s although
the logic chip can also be a 4081, 4077 or a 4001.
[The CD4070 contain four independent (XOR) Exclusive-OR gates].
I understand that Andrew F is a fan of "Lunetta Synths".
The module takes two input signals and divides them down by /2, /4, /8 & /16.
It also ring modulates the two signals and all of their divisions (similar to the ring mods in the Korg MS-20 and ARP Odyssey). All of these signals can then be mixed to create the output waveform.
This is a early video of one in action with some Serge gear:
There is a Euro version of this and I think Andrew F of NLC is still selling DIY PCBs for this module.

Below are some videos of the Divine CMOS with a Phenol from Kilpatrick.
I'm dividing the harmonics from VCOs 1 & 2.

Korg KPR 77 Drum
The KPR stands for Korg Programmable Rhythm.
She came out in 1983 and was Korg's response to the Roland 606.
It's very underrated. Each drum sound's level can be individual mixed via the sliders.
The sliders are just like the ones found on the Roland 707.
It's sounds consist of bass, snare, two toms, open and closed hi-hats, accent and (switchable) cymbal/clap.
The bassdrum is a bit weak in my opinion. The Toms aren't too bad.
Sadly no midi or DinSync- It's a Korg sync Korg uses a 48 ppqn (parts per quarter note) DIN standard whereas Roland's is 24 ppqn. For correct tempo match it is possible to use a clock synchronizer like the KMS-30 or an Arturia Beatstep pro.
There is a accent for each instrument.
We have flam repeats for tom1 & 2. There are also 4 different resolutions:
16th, 16th triplet, 32nd and 32nd triplet
The MEMORY has 48 basic rhythm patterns
- 32 steps for each pattern
There are 6 chain banks divided into Chains 1 & 2 & groups A, B, & C.
The Toms are also great triggers for analog gear. The 2 trig outputs are pulses of +5V ... so quite good for triggering EuroRack modules like envelope generators and Korg Volcas.

- 2 trig outputs (pulses +5V)
- start-stop pedalswitch input
- sync IN / OUT
- tape interface - See more at: http://www.polynominal.com/korg-kpr77/#sthash.YA3fG1Gx.dpuf

- tape interface - See more at: http://www.polynominal.com/korg-kpr77/#sthash.YA3fG1Gx.dpuf
Runs on 9V DC (original model KAAC 001) or 4 X 1.5V batteries
- tape interface
Patterns can be saved to magnetic tape if you have to turn off the machine without batteries.
There is a large display: - used for programming like in the Roland 505 & 626.
There are 2 recording modes: realtime record or step.
There is a accent for each instrument.

New Sound Waves - Sunday 12th July Meeting
I had the best Sunday ever.
Lot's of synths and good friends.
Above is a Buchla 200/ 200e - Thanks Paul.
Monome + Euro = :-)
New Sound Waves live at 107 Projects,
Redfern St, Redfern. Sydney, Australia.
We all got to see the new Roland AIRA Eurorack gear, thanks to Christian Moraga and Roland Australia.

Kilpatrick Phenol Synth - First Impressions
This just arrived yesterday. So I did a few quick videos
This second video uses a NLC (NonLinearCircuits) sequencer - The Bibdubba 1 & 3.
The Phenol is a modular that punches well above it's weight,
Andrew has done a great job.
