"Buchla Frequncy Shifter / Balanced Modulator Model 285e
perfect condition, v30 firmware"

via Buchla

"The top section of the dual-function 285e performs frequency shifting; up and down outputs are simultaneously available. The reference frequency can be externally applied or internally generated; the latter can be voltage-controlled and modulated using FM.

The bottom section is independent, and functions as a balanced modulator of the applied signals. The degree of modulation is voltage-controlled, and the reference frequency can be internally generated or externally applied, as with the frequency shifter. A separate audio output is dedicated to classic ring modulation, a subset of balanced modulation.

All settings of the 285e can be stored and recalled as part of a preset using the 225e or the 206e Preset Manager."

"perfect condition, v30 firmware"

via Buchla: "The 291e Triple Morphing Filter comprises three voltage-controlled bandpass filters that can operate independently or in parallel.

The amplitude, center frequency, and bandwidth of each filter may be independently voltage-controlled, and each can be modulated with externally applied signals.

The morphing capability might best be described as moving through a series of filter snapshots, with each snapshot consisting of a complete description of the filter parameters, and with each parameter continuously varying between snapshots. Morphing is accomplished with an applied voltage, or alternatively can be initiated with a pulse, with each stage’s time independently set. Up to eight stages may be employed.

All of the 291e’s settings can be stored and recalled using the 225e or 206e Preset Manager."

" Up for auction is a SCI Prophet 3000. These samplers filters are analog and sound amazing with there Curtis CEM chips same as Prophet 5 they are very warm and smooth and sound nothing like more recent digital filters and miles ahead of software samplers. There were only three 16 bit samplers that had analog filters to my knowledge The CMI Fairlight the EMU Emulator 3 and the SCI Prophet 3000. They all eventually replaced the analog filters with digital ones in later models and the sound was never the same.

This unit is in excellent condition both function wise and cosmetics. It was just serviced this week by Tom Virostek of Straylight Engineering. Tom replaced Several caps on Power Supply and main board. Also added more robust voltage regulators. Everything works as it should. Very shortly Tom will be offering a very nice memory upgrade for the 3000 check out the website for more details. A very nice guy by the way who does great work. I am also including a very large library over 120 disks of some great samples from Mini Moogs to Pianos The only thing Ive found is that sometimes floppy disks need to reinserted into the Floppy drive as they don't read properly. The Prophet also has most parts still available through Wine Country in Northern CA

The Prophet 3000 sounds truly awesome and in my opinion is a sleeper of a classic"
