"Extremely rare and sought after RSF MODULAR 11 (only 20 Systems made) from 1976. THE Father of KOBOLs, EXPANDERS and POLYKOBOL. That system contains 3 VCO 11, 1 VCF 11, 1 VCA 11, 1 GEU 11 ( ADSR + AR ), 1 ALIM 11, 1 Multiples + 2 CV in + 2 Gate in, 1 VCP 11, 1 VCP 12 ( 2 EXTRAORDINARY Analog phasers / flangers with a GORGEOUS SOUND ) The system is built in a lovely wooden case. As in an ARP 2600, some modulations are prepatched for some modules. The sound is Massive and Wonderful! Nevertheless, it will need a good synth technician WIZARD to precisely Tune and Calibrate the VCOs as they are really ' out of tune ' at the moment! You can see some pictures of the individual modules on the official RSF Site. Runs on 220 V. Cosmetics very good. Needs tuning and calibration. In northern France. Collection by VEMIA should be possible."

"For sale here is a RSF Modular 11 system which contains 8 modules + a multiple patchbay underneath. System has 2x VCO, 1x GEV(env), 2x VCA, 1x MNT(mixer), 1x VCF, 1x ALM(power supply).The modules need to be wired again, some minor repairs and calibration need to be done to get this fully functional again. Not many of these modules were produced during 1977-1978. Only about 300 modules maximum, and that for a total of 20 systems worldwide. So these RSF modules are even rarer than old Buchla modules, which were produced in quantities of 500 modules. This is certainly a great addition for the real analog purist who wants something different than the mainstream modulars offered today. The VCO's have a very fat sound and the frequency level that can be reached is amazing. RSF Modular 11 doesn't realy pop up everyday, it's just pure luck that there is another Modular 11 here on Vemia, otherwise it might take you ages to get your hands on one. A picture will be on display asap."
