About Syntheogen

Updated January 5, 2025

Syntheogen™ is a music sequencer and synthesizer for Android phones and tablets. It offered sampling and subtractive synthesis like other apps, plus advanced composition features like polyrhythms, custom time signatures, and automatic transposition:

The app is no longer available on Google Play. I didn't really enjoy working on it, Android development is a nightmare, and there are definitely easier ways to make money. I will open source it when I get some time.

Features

• Produce classic analog sounds with the two-oscillator polyphonic subtractive synth;
• Import, trim, and loop samples with the built-in sample editor, then play them with the simple sampler;
• Combine subtractive synthesis and sampling with the hybrid sampler;
• Create menacing growls or piercing spectral shrieks with self-oscillating filters;
• Add bite to your sounds with FM or AM synthesis;
• Shape sounds with two LFOs, each capable of targeting multiple parameters simultaneously;
• Create as many tracks as your device can handle;
• Apply effects to loops or tracks, and use as many as your device can manage. Effects include clipping, reduction, flanger, chorus, filter, comb filter, tremolo, delay, and reverb;
• Edit every note in the loop from one place with the multitrack step sequencer;
• Program triplets with ease or work in unusual time signatures with step guides;
• Create sophisticated polyrhythms by joining tracks of different length in the same loop;
• Gain detailed control over pitch bends and note dynamics with step ties;
• Transpose compositions to different scales or modes with just a few button presses;
• Turn loops into complex, dynamic compositions with the song editor;
• Export finished loops and songs to WAVE files for external playback;
• Get fast answers from the detailed, context-sensitive, in-application help;
• Learn more by consulting the extensive online user guide;

Syntheogen uses Deja Vu Sans. It was developed with the help of GIMP, Inkscape, ImageMagick, Audacity, WinMerge, GLee, and the KVR Audio forums.

Many Syntheogen drum samples were adapted from the Open Source Drum Kit. Syntheogen's filters derive from the 'RBJ' filters created by Robert Bristow-Johnson.

Thanks to all who contributed!
