The Tempest is no slouch at polyphonic synth duties.
Several years ago I was looking for a poly synth that had deep programming capabilities and an out-of-the ordinary oscillator section. The Poly Evolver seemed like the way to go back then but after taking a closer look at the specs on the Tempest the synth architecture seemed in the same general ballpark as the Poly Evolver even without the free running LFO option so I opted for the extra two voices and tried it out. It was a blast to program and after a few days it was clear that it was deeper and more powerful than any of the polyphonic synths I had at that time. With it’s 4 OSCs (2 analog, 2 digital 450 samples) 2 LFOs , 8×8 mod matrix, 5 envelopes , low pass and high pass filters, sequencer, effects and individual outputs there is enough there to keep you busy for years.
The Tempest was designed for different users than me. It was designed for people who would use it as a rhythmic instrument and a lot of the performance features were wasted on me. I used it more like an MKS-7 module, a multitimbral box with multiple outs for synth and drum parts sequenced externally. DSI have a million other choices for poly synths but for someone out there who is looking for a desert island synth that can do double duty it’s an interesting option.
The Tempest as a synth can cover a certain subset of the sonic territory as the Poly Evolver. One feature that I like is how you can have the two digital OSCs signal kept outside of the filter path that the analog OSCs is on so sweeping the filter would only affect 2 of the 4 OSCs. Another bonus for having so many envelopes is controlling the pitch of each OSC with a different envelope. I created a set of synthesizer presets for the Tempest that can be downloaded here http://sellfy.com/p/PXYS
I wanted to mod a midi controller that had nothing but keys on it but the Arturia player 25 was the closest I could find. I swapped out the LEDs, added wood sides, painted it to match and the good folks at DSI sent me some Tempest knobs. Today I would just get a MophoX4/SE to use with it. Maybe they’ll make a Tempest Keys version.
