Roland Guitar Synth US-2 Unit Selector Switcher & C-24C 16 Foot Latching Cable

US-2 via this auction

"If you have the embarrassment of riches of having two different guitar synthesizers that you want to drive from one guitar, well, you need this box!"

Pic of the inside below.

C-24C via this auction

"This is a latched male to female cable that is around 16 feet in length. This is the basic standard cable that was supplied with units back in the glory days of hexaphonic guitar synths. This was in the storage of an ex music equipment dealer along with the switcher that is also listed at this time."

This is a supporting member listing.

Oberheim DS-2A Vintage Digital Sequencer

via this auction

"The rarest of rare, The DS-2A is a pre- digital music sequencer. Designed and built in 1974 by Tom Oberheim , it is considered one of the first ever digital musical sequencers. It pre-dates Tom's famous SEM and was Tom's first real synthesizer product. The DS-2A is capable of storing and sequencing 144 notes and provides a single channel of CV/Gate input and output."

Sequential Circuits Prophet 5, Rev 3.3 w/MIDI SN 4856

via this auction

"Beautiful vintage 1983 Sequential Circuits Prophet 5, rev. 3.3 with factory MIDI and expanded patch memory storage (120 programs instead of 40 on previous versions). This synth is in great shape both functionally and cosmetically, last serviced about 5 years ago at Borish Electronics in Chicago. The original flight case is a little beat up but still 100% functional. Great opportunity to own one of the most iconic synths of all time at a reasonable price."

Roland JX-3P Original Music Demo 60 FPS Video

DRUM MACHINE Review and Buyers Guide Part 1

video upload by Noisegate

"Drum machines have come a long way in a relatively short period of time. If you think about the first fully programmable drum machines such as the Roland legendary TR-808, that was only a little over 40 years ago. Roland’s first MIDI drum machine, the House and Techno queen that is the TR-909 was manufactured in 1982. It’s nice to reminisce about the 1980s when drum machines became popular, although there’s been some modern classics during this millennium including the Elektron MachineDrum from 2001 and Dave Smith Tempest from 2011. Today there are a plethora of new drum machines all with amazing new features. Yes, many manufacturers these days politely provide a nod to the classics such as the 808, 909 and LinnDrum through to the modern classic in their designs. Here is our mega drum machine guide for the current drum machines that are being manufactured. This project became so big, that we had to split it into two parts, so here is part 1:

Check out the specs and the bits we love from each of these drum machines here:

If you think that was mega, we’ve still got plenty more. We’ll be covering the Roland TR-8s, Korg Drumlogue, Erica Synths Perkons and more in part 2...!!

Another one spotted by M Me.

video upload by EMEAPP

"This little gem has to be one of our favorite purpose-built performance synths here at EMEAPP. It is the KORG Synthe-Bass SB-100, first released in 1975. Ideal for live performance, the SB-100 is a single oscillator bass synthesizer monster which offers an extremely powerful low pass filter "traveler" as well as a plethora of wave forms and modifiers to choose from to create monstrously fat and punchy bass tones. In this video, electronic music pioneer Don Slepian will demonstrate the SB-100 and the range that this compact little box can cover."

"The goat. It sounds amazing. Local pickup only. The faceplate is in gorgeous shape. the wood is in great shape with a little scuffing. Lid and outer shell has some scuffing. No legs or pedals. Local pickup only. Come try it out and be amazed beyond words.

Works perfectly. A few buttons are a touch sticky. Memory 3 button sticks and has to be gently worked back up. I have included a demo putting this through its paces."

Never heard it called the goat before. Somone once referred to the Korg Maxi Korg 800DV as the goat. You can find a handful of goat posts here.

Demo posted here

"Also sold as the ARP Quartet this keyboard offers 4 parts: Brass / Strings / Reed / Piano
Nice moogish filter on the brass part and the strings sounds are not too bad either. They do use the same TCA350 BBD chipsets as other classic string machines like the Eminent Solina, Logan String Melody or Crumar Performer."
