Sequential Circuits MAX

“This Synth has been modified with the addition of the following features:

• 100 sounds, all downloadable, located in battery-backed RAM

• Note storage increased from about 500 to about 3200

• Unison mode added.

• Three sets of 100 factory sounds in EPROM: 80 Max + 20 Six track Unison factory sounds, 100 Six Track factory sounds, and 100 Multi-Trak factory sounds (without chorus or velocity sensitivity, of course)

• CC parameter changes to current program can be saved to program 99, then copied to any other program

• MIDI receive buffer increased from 64 bytes to 128 bytes

• Removed code that reduced volume of subsequent notes if CC change received while MIDI note with low velocity playing. This a code bug in the original EPROM.

These features were added by upgrading both the EPROM and the type/amount of RAM. The Max shipped with a 128K EPROM and two 2Kx8 SRAM chips. This modified Max has a 256K EPROM and a single 32Kx8 SRAM chip (only 16K is used). The modification is a small PC board which holds the EPROM and NV SRAM. This board plugs into the existing EPROM socket on the Max. Five additional wires connect from the Max main board to the new memory board. In addition, the two SRAM chips on the Max main board have been disabled. See more info by googling “Sequential Circuits MAX Mod Page – Tauntek”

INCLUDES:
-Synth
-Manual
-Power Adapter

ABOUT THE SEQUENTIAL CIRCUITS MAX:

The original NON-Modded Sequential Circuits Max was designed as a companion to the Six-Track, Multi-Trak and possibly the C64 personal computer. It relied on MIDI messages for parameter changes, having no on-board way to vary them. It came with 80 “factory sounds” in EPROM, and storage for 20 more in RAM, which could be used after downloading via MIDI. Two “songs” or sequences could be recorded and either stored in RAM or dumped to MIDI. No battery back-up was provided for RAM, so all song data and the 20 programs were lost when the unit was powered down.

Synth is in great working condition. Guaranteed to be operational. Returns accepted if Synth is not working as described.

Swapping voice chips did not resolve this. Currently has ROM 11. Some scratches are shown on the top panel. Two side screws are missing but does not affect stability.”

Oberheim Matrix 6

“Up for sale is the legendary oldie but goodie,oldie but basically like new goody if you can believe it. The Oberheim Matrix 6. Yes im talking about a basically untouched classic piece of vintage gear in basically new condition !!, This piece has never been serviced, repaired or never even been played for more than even a few hours in TOTAL. So in other words its basically like walking into a Sam Ash or other music store between 1984-1987 an asking “may I please have a Oberheim Matrix 6″. I was thinking about keeping it as a show piece because of its age and history, and not to mention it is sort of a family heirloom, but I need to buy other gear, I have shown numerous pics in this posting but if you require additional pictures please don’t hesitate to ask, and that goes for any additional questions too. Included is the original foot pedal and power supply, sorry but I don’t have the manual, I don’t know what happened to it, but it can be downloaded online free of charge.”

Several years ago, I had a very experienced synth tech install the KiwiTechnics ‘Kiwi-3P’ daughterboard into it.

Roland JX-8P

“Re-listed due to abject time waster.

I’m parting with my old friend, the Roland JX-8P. It’s been very well used, gigged all over the place.

It came from the USA so will need a power converter which I’ll throw in. It’s late 80s but I’m not sure of the exact date. 86 is in my mind from when I picked it up but don’t quote me.

Pros – presets are great, and editable. Midi compatible. Great responsive keyboard.

Cons – the aftertouch sensor is goosed, and I got a bit excited one night with the pitch bender and snapped it off so screwed it back in but the screws were too long and visible from the surface.” Click here to search for synths on eBay

Roland Jupiter 6

“Roland Jupiter 6 Analog Synthesizer in perfect working condition. I am not the original owner but have had it in my studio for a while and it performs flawlessly. Never taken out of my home. Cosmetically I would rate this unit a 9/10. There are a few small scratches on it, which are to be expected on a 36 year old keyboard.

The last picture is of a device I made. When the Jupiter powers up, it is in midi omni mode. It receives data from every channel. To bypass this, you need to plug in a midi cable from the in to the out and power up. Then it will only transmit on midi channel one. I made this box so I wouldn’t have to keep plugging and unplugging midi cables. So I switch the box to off, turn on the unit, switch the box to on and perfect! It’s only on midi channel one. If you don’t use other midi channels, you won’t needs this. This unit does NOT have the Europa mod upgrade.”
