SynthJacker is an autosampler for iOS. It automatically plays back a MIDI sequence with the notes and velocities you specify, and records the results into an audio file. It then slices the audio into individual sample files, ready to import into an iOS sampler app of your choice.

SynthJacker supports both internal instrument Audio Units (AUv3) and external hardware synths. Additionally, you can export a MIDI file with the desired notes and record a synth playing it back, then bring it to SynthJacker for slicing.

You can save presets of your sampling sessions, including the note range, velocity layers, and note durations. You can also apply post-processing to samples, to trim silence from them or normalize their level.

SynthJacker automatically names the resulting sample files with note and velocity information, so that they can easily be automapped by a sampler app. It also writes an SFZ file with sample information as regions and their root keys and velocity mapping. You will find the results in the iOS Files app, in the SynthJacker folder of your device.

What's new in version 0.8.2
- Fixed a problem with hardware sample rates. Previously SynthJacker would try to set the hardware sample rate to 44.1 kHz. On newer devices the sample rate is fixed at 48 kHz. This could result in samples being out of tune.
- New sample post-processing engine with better visual feedback.
- Added input level meter.
- Note sequence name now follows the selected factory preset on instrument Audio Units.
- Added option to clean up temporary files (in Settings menu).
- Added alert for missing microphone permission, in case it was turned off after it was initially granted.
Our verdict: Good
  • + SynthJacker is a highly rated app (5-star).
