Mini Synthesizer 4+

Electro-Harmonix, a pioneer since 1968 in the field of sound effects pedals for musicians, has produced an app which is a faithful digital re-creation of their circa 1980 analog cult-classic, The MINI-SYNTHESIZER.

Available for iPad and iPhone (IOS version 15.0 or later), the EHX MINI-SYNTHESIZER accurately delivers all the vintage synth sounds of the original plus modern updates.

EHX President and Founder, Mike Matthews stated: “Fans of vintage synths will appreciate the apps ability to recreate the original’s warm analog sounds and deep funky bass, but because it’s so affordable ($2.99 for phone, $4.99 for tablet) and user-friendly, parents, educators and non-musicians will love it, too.”

The MINI-SYNTHESIZER app comes with 25 presets and the ability to store an almost unlimited number of user presets programs. Audiobus capabilities are also included.

Intuitive, flexible and powerful control are provided by the MINI-SYNTHESIZER’s 12 sliders and nine switches. Here’s a breakdown of the user interface:

OSC Section
- PITCH slider lets the player raise or lower the pitch of the note by +/- 1 octave
- SUB-OCTAVE slider introduces a note one octave below what’s being played for extra bottom
- OCTAVE UP switch causes the note being played to jump up one octave.
- TUNE knob lets the player tune the MINI-SYNTHESIZER to other instruments and sound sources over a +/- 50 cents range.

LIMITATIONS
- InterApp Audio experiences periodic crashes and graphics issues.
- The MINI SYNTH runs at 48 kHz sample rate; using the MINI SYNTH in an environment with 44.1 kHz sample rate (such as Garageband for iOS) may cause aliasing.
- Presets saved in the standalone app cannot be accessed when using the MINI SYNTH as an AudioUnit, and vice versa.
