SynthJacker is an autosampler for iOS that allows you to easily record and slice audio samples from MIDI sequences. Whether you're using internal instrument Audio Units (AUv3) or external hardware synths, SynthJacker has you covered.

With SynthJacker, you can specify the notes and velocities you want to capture, and the app will automatically play back the MIDI sequence and record the results into an audio file. It then slices the audio into individual sample files, which can be imported into any iOS sampler app of your choice.

One of the standout features of SynthJacker is its ability to export a MIDI file with the desired notes and record a synth playing it back. You can then bring this MIDI file to SynthJacker for slicing, making the sampling process even more streamlined.

In addition to its sampling capabilities, SynthJacker allows you to save presets of your sampling sessions, including the note range, velocity layers, and note durations. You can also apply post-processing to your samples, such as trimming silence or normalizing their level.

The app automatically names the resulting sample files with note and velocity information, making it easy for sampler apps to automap them. It also generates an SFZ file with sample information as regions and their root keys and velocity mapping. You can find all the results conveniently stored in the SynthJacker folder of your device's iOS Files app.

If you're looking for a powerful and user-friendly autosampler for iOS, SynthJacker is definitely worth considering. Its seamless integration with MIDI and sampling capabilities make it a valuable tool for musicians and producers alike.
