User Reviews

Reviewers praise SynthMaster Player for its rich sounds and expansive preset library, AUv3 support, and a sleek, user-friendly interface. However, recurring issues include crashes and startup problems, presets failing to load or sound after restarts, and unreliable restoration/purchasing of presets across devices. Update-related preset loss and cross-device compatibility concerns (BeatMaker/DAWs, Bluetooth) also surface. Overall, the sound design and UI are strong, but stability, preset management, and cross-device purchasing reliability need improvement.

Pros

Rich, high-quality sounds and a large preset library.
Great value with affordable add-on packs (IAP).
AUv3 support and solid DAW integration.
Sleek, user-friendly GUI and interface.

Cons

Frequent crashes and launch failures (app closes or won’t start).
Presets sometimes stop working or don’t produce sound after reopening.
Purchase/restore problems (download errors, re-purchases, lost presets after updates).
Presets/favorites can be lost after updates requiring re-setup.
Compatibility and integration issues (BeatMaker/DAW integration, Bluetooth keyboard, inter-app audio).

Dev reported 11 months ago bug fixes to patches not playing sound. Problem not only still happening but gets worse every time I remove and reload software. Need to fix this.

Love the sound on the presets that work, but some presets stop working. After the initial use of them, upon closing the app and reopening it, about 50% or more of the presets don’t produce any sound.
