Prism review
A $99 plugin for turning instrument recordings into editable MIDI.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Prism is a Windows and macOS audio-to-MIDI plugin for producers, musicians, educators, and transcribers. It analyzes recorded audio for pitch, timing, and dynamics, then generates editable MIDI note events. The software is designed primarily for isolated or solo recordings of instruments such as guitar, piano, bass, saxophone, trumpet, and violin. It handles both monophonic and polyphonic material, making it suitable for turning recorded performances into MIDI that can be corrected, arranged, or used with software instruments.
Pricing is straightforward: the Free Trial is fully featured for 21 days, while the Prism plan costs $99 as a one-time purchase. There is no free plan. The paid plan includes Windows and macOS versions, VST3, AU, and AAX formats, plus ARA and traditional insert-plugin workflows. DAW compatibility includes Pro Tools, Cubase, Nuendo, Reaper, Studio One, Logic Pro, and Cakewalk Sonar. The published plans make Prism a purchase for producers who expect to use audio-to-MIDI conversion regularly rather than a low-commitment utility.
Its strongest workflow features are the built-in editable MIDI editor, drag-and-drop MIDI export to a DAW, MIDI file saving, and multiple algorithms for general material, distorted guitar, and grand piano audio. ARA mode can fit supported DAWs, while traditional plugin insertion covers other workflows. Prism is less suitable for users who need readable notation export or a broad batch-processing tool; its documented output is MIDI, and its focus is individual instrument recordings. Choose it for editable MIDI inside a DAW, especially when polyphonic conversion and plugin compatibility matter. Choose an alternative if notation output, batch processing, or a free plan is essential.
