Conifer Productions Oy released SynthJacker as a way to easily sample hardware synths to create SoundFonts. This includes samples with different notes and velocities. It's a surprisingly clever little app. There's even a demo video below to show it in action.
If, like me, you're curious about the Oy at the end of the company name; it is short for Osakeyhtiö. This is the Finnish equivalent to LLC or GmbH, which just means a limited corporation. My dog walking business was an LLC, so people couldn't sue me personally if something happened to their dog!
SynthJacker iTunes Description:SynthJacker automatically plays back a MIDI sequence with the notes and velocities you specify, and records the result. It then slices the audio into individual samples, ready to import into an iOS sampler app.
SynthJacker also writes an SFZ file with sample information as regions and their root keys. You will find the results in the iOS Files app, in the SynthJacker folder.
SynthJacker automatically names the resulting sample files with note and velocity information, so that they can easily be automapped by a sampler app.
SynthJacker lets you save presets of your sampling sessions, including the note range, velocities, and note durations.
