Synclavier Pocket! is a demo app that re-creates the Synclavier® II Digital Synthesizer of 1980 in shirt-pocket form. The original instrument burst upon the music scene in May, 1980, and ushered in the digital musical instrument revolution of the following decade.

Synclavier Pocket! presents the “panels” from the original Velocity-Pressure Keyboard (VPK) button surface adapted to the highly sensitive gesture recognition system of the iPhone. Under the hood is the powerful CSynclavier DSP Engine, complete with Partial Timbre, Timbre Frame, FM-Synthesis and Additive-Synthesis methodologies.

But there is more! The original Synclavier® hardware offered 8-bit audio resolution - just enough to create rich strings, robust pads and sci-fi effects that were, above all, interesting and attention-getting. In the day we dreamed of 10- and 12-bit audio resolutions; we knew they would offer tremendous sonic potential, but could not be realized on the hardware of the era. You want grunge? Try the 4-bit setting! Silky smoothness is at the 12-bit setting.

The free download includes access to the 64 Timbres that were on the original factory “System Disk”. (“Preset” was an unknown word at the time, so we called each sound a “Timbre”). In-app purchases give you access to the 9-volume FM Timbre Library and the 6-volume Resynth Library. “Resynthesis” was a hybrid form of sampling combined with synthesis and was first developed by New England Digital in the 1980s. External MIDI keyboards, Ableton Link and Audiobus are all supported in the free download version.

The Timbre Design and Save features of Synclavier Pocket! are available by an additional in-app purchase. Go ahead - Turn My Knob!

The Synclavier® knob is as unique today as it was revolutionary at the time of its introduction. The knob is a rate-of-change controller; close your eyes and let your right-brain kick into the sound design process. Forget the numbers; forget the digits; let your ears guide the process. Sound design with a touch-screen and Synclavier® knob is as different from a mouse-driven GUI as, well, Synclavier® was different than the Fairlight CMI!

Amazing piece of work

I really enjoy playing with this app, but what I feel like it needs is a sampling based system where you can implement, play, and resynthesise almost anything just like Arturia’s Synclavier. Adding in the base samples from the original Synclavier II would also be a plus.

Good App that Won’t Exit

I cannot exit out of this app! I have to reboot iOS Xr every time.

Harrison Floored ,

Wait till they work out the kinks.

So, downloaded the free version. Some of the sounds are nice, some are totally out of pitch or volume range. Some are mis-named as flute when they are more like a Farfisa.

The biggest problem is no way to slide the keyboard into a higher range that would better suit some of the patches. Maybe they're supposed to reflect limitations in the actual machine, but just about every ios synth I have has some way to slide the keyboard into a higher octave. The built-in help is kind of lame.

I think we could do better, guys.

Developer Response ,

Thank you very much for your input. Our new build due out later this week includes a Keyboard Slider to adjust the range of the on-screen keyboard. If you hook your device up to a pair of studio reference monitors and use an external MIDI keyboard you will hear the Timbres with a whole new level of excitement and clarity.

With respect to the volume being out of range, if you use an external MIDI keyboard with velocity you will have much better control over the loudness.

Thank you again for your comments and I am glad you enjoyed the free download!
