"This amazing PPG Wave 2.3 has received the full Synthropology™️ treatment.

"1980s Amdek Rhythm Machine RMK-100 vintage drum machine in exceptional condition and in perfect working order. This early programmable drum machines was produced by Roland under the Amdek (later rebranded to Roland DG) banner from 1981-83, a subsidiary created exclusively to produce early computer monitors and small DIY music kits. The RMK-100 is particularly rare among analog drum machines due to its limited release and the fact that it was only produced in a kit form. It’s a step-write-style drum machine, designed to compete with the likes of the Boss DR-55.

The RMK-100 features Bass, Snare, and Open and Closed hat sounds, all distinctly warm and analog-sounding. Considering its era of production, The RMK-100 is an exceedingly versatile little machine; the Bass drum has internal trimmers for Level and Decay, and the Snare has a trimmer for Noise Level, allowing for excellent tonal sculpting capabilities. It’s a completely programmable machine, with 8 banks of 16-step pattern creation capability.

Controls are relatively simple: the four drum sounds are selected at the four-way “Sounds” switch, and the user inputs the sounds into the 16-step sequence through the two buttons (which also function as Start and Stop/Reset buttons when Play mode is engaged). A unique function of the RMK-100 is the “Filler” switch, which divides each 16-step sequence into 2, 4, or 8-step chunks and then cycles through the resultant sequences at an adjustable rate. The 8 banks are selected at the rotary bank on the right side of the unit, and there are individual knobs for Volume (also functioning as the Power switch), Accent, and Hihat Level."

Pic of the inside below.

"This was bought brand-new in August of 1983 and acquired from the original owner. It is as close to a time-capsule piece as I’ve ever seen and I’ve had 10 LinnDrum’s in the last 3 1/2 years alone. There are just a few very fine marks on the face (the small flecks in the 2nd photo are just dust) that keep it from truly being ‘mint’ which is pretty wild because the original owner actually used it. These were $2,700 back in 1983, which is over $8,000 in today’s dollars, so it’s not surprising someone took great care of it. It has been meticulously restored and is functioning as well or better than it ever did even back when it was brand-new! The circuit is unmodified to retain it’s original spec and for the fact it is so well-preserved. Another huge bonus is the individual tuning pots for the voices actually function properly and sweep with consistence. A vast majority of these machines have some degree of instability in the tuning pots due to age (DeOxit does not normally fix this issue). Not this one, though. A true collector‘s piece and one you can actually use consistently.

- Full electrolytic recap

- Auxiliary board cleaned and refurbished with battery holder and new rechargeable batteries

- All buttons cleaned and rebuilt

- All 32 faders removed, disassembled, cleaned (and repaired where necessary), lubricated, greased, and rebuilt

- ZIF quick-release sockets added to 7 voices (bass, snare, congas (x2), toms (x2), and clap)

- Factory presets reloaded

This classic piece is essentially ubiquitous with popular music starting from the day it was released. Nearly every major label recording artist and/or band used one of these somewhat extensively (that had hits, anyway). Part of that is due to Roger Linn & Co. dishing them out like tic-tacs in order to promote the machine, but that’s beside the point. The fact of the matter is this machine is all over so many songs, it would be nearly impossible to catalog them all. It’s a who’s who list of household name because it clearly made the impression they’d hoped. And the best part about it is it’s as relevant to today’s scene as it was back then. You can even swap in sounds from your other favorite drum machines to create a truly versatile, desert island instrument!

Most of these are banged up, corroded from battery acid leakage, modified poorly, unrestored, or all of the above. This is the nicest, most-complete LinnDrum available anywhere in the world. Includes original box, sales receipt, user manual, promotional paperwork, and cassette with pre-sets."

Cherry Audio PS-330 (No Talking)

"Emulation of the colossal and ultra-rare semi-modular analog polyphonic synthesizer released by KORG in 1977"

See the announcement post here, and Resonation preset pack demo here.

"PS-3300 Features
Exactingly faithful virtual analog emulation of the semi-modular analog polyphonic synthesizer released by Korg in 1977

Three independent "signal generator" panels, each with an oscillator, lowpass filter, three-peak resonators, envelope with velocity, amp, two mod generator LFOs, and per-note tuning:

3X VCOs with six waveforms: triangle, saw, rectangle (square), two preset pulse waves (with different widths), and PWM (variable-width pulse)

3X resonant VCF 12 dB/oct lowpass filters with the option to select between the standard "clean" PS filter or the "crunchier" MS-style filter

3X modulatable "triple resonators": 12 dB/oct bandpass filters to produce vowel and phasing tones

3X discreet ADSR-type envelope modulators with velocity control, and amplitude modulation

3X two syncable "mod generators" (LFOs) with output jacks: one with triangle, saw, ramp, rectangle, pink noise, and white noise, and the other with triangle waveform

3X temperament section with individual tuning knobs for the 12 chromatic notes, and temperament presets for Equal Tempered, Mean Tone System, Hepatonal System, and Just Intonation

Copy/paste settings from one signal generator panel to another

Polyphonic mode with up to 24 voices of polyphony and three monophonic modes: last, low, and high note priority

Semi-modular synthesizer with virtual jack and cable system, featuring unlimited mults per jack and customizable (color, transparency, animation) cables

Master signal mixer panel with sample & hold, general envelope generator, and two control voltage (CV) processors

Individual channel panning

User-selectable bend range and master tune

Studio-quality integrated effects: chorus, echo with sync, and three types of reverb (spring, plate, and Galactic)

Over 360 professionally designed presets in a dozen categories. These include a bonus Legacy collection of basic presets based on the patch sheets in the original PS-3300 Owner's Manual, a 3100-based Glissando patch, and a 432 Hz Equal Temperament patch, all to get your started in your own sound design adventures.

Standalone virtual instrument and plug-in versions

Cherry Audio’s popular Focus zoom-in feature, as well as standard UI zoom and resize via drag

Also available: With its three-synths-in-one architecture, unique resonators, and semi-modular nature, the PS-3300 is truly a behemoth of synthesizers. Sound designer James Dyson's Resonation Preset Pack (sold separately) includes additional presets that go further into the relative dimensions between light and shadow and all the way to the outer limits."

Blue EML Electrocomp 100

via this auction

"Rare as hens teeth, the EML Electrocomp 100 was EML's second synth, only preceded by the 200, both of which were blue and only made for universities, the 100 preceded the 101 and supposedly less than100 were made in 1970 before they started selling to the general public. this one has a few mods on it, first osc 1 is hardwired to share the noise in the mixer section, so you can choose noise or osc1, there are switches to turn off each of the 4 oscillators, there is also a direct output added and a switch that turns off the VCA outputs, not sure why exactly this was done. The unit does seem to work completely as it should after giving it a good 30 minutes to warm up, however I do know the pots need to be cleaned, especially those in the envelope section as sometimes those pots specifically can cause certain functions not to work, usually if you spin the pot back and forth enough, they will come back but then definitely need a cleaning, he it's 53 years old! The pots are sealed, so they can either be drilled and creaned or carefully taken apart and cleaned, I figure I will leave that up to the new owner, given the age of the synth it is sold AS-IS, given the rarity of this piece I will be asking a lot as I am not eager to sell it, it is the only one I have ever seen in my lifetime. I will pack and ship extra carefully with this one and fully insure it, so you can buy with confidence on that front!"
