son of 4 voice
price : $3,995.00
four classic synthesizer expander module (sem) synth modules
sems are 100% discrete analog - no custom chips
new state of the art voice control & programmer retains all features of the original four voice programmer and keyboard control modules while adding new capabilities
so4v may be used as a four-voice polyphonic synthesizer or as four individual synthesizers under midi control
two midi sync capable lfos with multiple waveshapes including sample and hold per voice
two programmable adsr envelope generators per voice
selectable master tuning (both vcos or vco2 only) allows easy detuning for huge unison sounds
polyphonic portamento with linear or exponential response
noise generator connected to filter input #1
external audio or a440 tuning reference connected to filter input #2
updated output module with mix and pan control for each voice
two so4vs can be easily connected together - result: eight voices!
signature plate--each so4v comes with tom oberheim's signature on the front
the combination of the sem's limited programmability, combined with programmable envelope generators and lfos in the new programmer, allows many but not all of the so4v's parameters to be remembered in memory
the most important parameters that remain non-programmable in the new son of 4 voice are resonance, filter modes, and initial pulse width.
this was the same situation with the original 4-voice, and while certain parameters remain non-programmable, enhanced features of the new programmer add capabilities that the old 4 voice did not have,
programmable or not. also, the patch storage in the new programmer is four-way multitimbral, so you can have a different setup stored for each sem in a patch.
there is also a complete midi implementation in the so4v, including lfo sync to midi clock and individual midi access to each sem voice. and the patch storage includes the settings on the enhanced keyboard
electronics / voice assignment section.
the so4v is a special machine - for ease of use and fast setup, it is outdone by numerous hardware and software synths conceived for the mainstream. but there is nothing on the planet that sounds like
