New Bubblesound LP40 Low Pass and HP40 High Pass Filters Based on the SSI2140 / SSM2040 Filter Chip

Priced at $169 USD each. See the dealers on the right for availability.

via Bubblesound Instruments

"The LP40 and HP40 are Low Pass and High Pass filters based around the SSI2140, the successor to the legendary SSM2040. The 2040 is the best sounding filter chip that came out of the 19070s and the 2140 takes the original design and adds CV controlled Resonance. The LP40 and HP40 are small format filters that do not cut corners.

The Input is set up like the Dual SeM20, when the indicator line is straight up the input is at full, anything past that will over drive the input. The Frequency CV responds to both positive and negative voltages while the Resonance CV is 0-10V. These filters will track 1V/Oct with internal temperature compensation.

There are 3 output types and 4 outs; 12 and 18db have one output each and there are 2 24bd outputs. While using the 24db output you can take the second and send it to the HP40 to create a variable band width Band Pass while still using the 24db Low Pass.

The LP40 is an exceptionally versatile filter capable of smooth and creamy basses and with a turn of the resonance pot it becomes dripping acid.I have wanted to make a 2040 based filter for many years and to be making the LP40 with chips from the original manufacturer is something bubblesound is very proud of. And unlike the original SSM2040, the LP40 has a bass compensation feature that keeps the resonance and signal level balanced all the way down.

The HP40 is a unique filter. There have been very few High Pass filters over the years, let alone ones that resonate. The High Pass filters in the Roland polys were crucial their sound and with the HP40 those types of sounds are easy to make. But the real magic of the HP40 happens with you turn up the Resonance and let it go; from fragile and brittle leads that vanish into the air to sweeps and hollow thumping kick drums the HP40 is in a class by itself."

P-600-G 1.0.1: Revised Randomize Program Settings Dialog

video upload by Mister 1-2-3-4 Programming

"I have updated the P-600-G VST3 plugin to build number 1.0.1! This is a quick demo of the cosmetic changes made to the Randomize Program Changes dialog: unlocked controls are now tinted red and the 'open lock' icons have been eliminated so that parameter values are not obscured as they change. Apart from that, the functionality is the same.

P-600-G is distributed free and open source under the GPL v3 license. You can download it and get more information about it at

Arturia have hooked me up with their V Collection library, I'll likely be going through the whole thing over the next month (with the exception of things like piano and organs). This was the most exciting instrument for me, I've been in love with buchla and west coast modulars for some time and arturia has done an amazing job replicating the sound and workflow. join me as I become more familiar with these synths"

DIY Build #3: Neutral Labs MEG Eurorack Waveshaper

video upload by Piotr Garbaczonek

Thanks for watching!
The Neutral Labs MEG kit finally arrived from Thonk from the UK and I was able to find some time and build it. It took me an hour and 47 minutes, and I captured the whole build but managed to condense the video down to 35 minutes. It has some skips and time-lapses, and some hair... I know, I am still getting used to shooting in this format, so I was getting close to the module a few times. Sorry about this. I will pay more attention in the future.
Find more information about the MEG here:

Oberheim Two Voice TVS-1A

via this auction

"Amazing, vintage, legendary, rare - the Oberheim Two Voice is the ultimate mono/duophonic synth!

The back panel has CV, Gate, and VCA in for each separate SEM, as well as an external clock in to the sequencer. The switch turns the panel on and off, allowing for easy switching between keyboard/internal sequencer use and external sequencing without plugging/unplugging cables.

Just serviced, comes with power cable, does not have original lid, will be packed professionally."

Custom Red Roland Juno-106

via this auction

"Completely overhauled Roland Juno 106 in a custom red livery. Synth is as close to brand new as you can get. This is not your average restoration and has countless hours of excruciating detail put into it. The power supply was fully rebuilt with 5000 hour Nichicon caps, all electrolytic and ceramic caps replaced along with the voltage regulators and dual regulator controller. All 17 original ALPS sliders were completely disassembled, thoroughly cleaned, lubricated with quality silicone grease and reassembled. They have an incredibly smooth and firm feel. The panel board also features 34 new tactile switches, and 3 new alps 2 position slide switches. The 3 mini sliders on the bender board were also disassembled, cleaned, and lubricated.

Every board was stripped, thoroughly degreased, and washed. They have a glossy sheen appearance like they would from the factory. All 6 voice chips are original and have had the conformal coating stripped. Each voice chip was completely reflowed and installed on pin headers for easy removal or swapping. The synth was burn-in tested for 8 hour periods on several different days, absolutely no issues. CPU board has new battery installed. The entire keybed assembly has been completely stripped. Every single key was hand washed/degreased and polished. The keys are the whitest I have seen, this board appears to have very little use and was kept away from the sun. All rubber dome contacts despite working, were removed, and thoroughly cleaned. The carbon tracks on the keyboard assembly were also cleaned. This is a future proofing process which will insure several more decades of reliable note triggering.

A 3 prong standard IEC receptacle has been installed and a quality brand new power cable is included. All solder joints have been inspected and common control areas have been reflowed. All potentiometers have been cleaned. Full calibration performed, no crackle in the chorus! The synth is 100% functional and is in perfect cosmetic and electronic condition.

This is a unique collectors piece."

A perfect instrument to fill out your studio arsenal."
