DeskTap Support

Version: DeskTap 1.0.0
Supplier: Goussi, trading as GridWave DSP
Support: contact@gridwavedsp.com

Supported environment

DeskTap requires a MacBook with an M1 Pro chip or newer running macOS 14.6 or later. The recorded hands-on configuration is MacBook Pro (M1 Pro) on macOS 26.5.2, using built-in speakers at 48 kHz with a 256- or 512-sample buffer. Other combinations in the declared range have not all received an individual hands-on test; use the trial on your exact Mac before purchase.

Bluetooth output, external audio interfaces, 44.1 or 96 kHz and a 128-sample buffer are not supported in this release. Wired headphones may work, but their latency has not been measured.

Getting started

1. Place the MacBook securely on a stable, flat and dry surface.
2. Launch DeskTap and read the first-run safety and privacy guide.
3. Choose one of the nine included packs from Sample Pack.
4. Press Calibrate, remain still during background capture, then complete five cycles of Light, Medium and Firm taps. Firm means the upper end of your normal range—not excessive force. Use only a light, controlled bare-fingertip tap when tapping the MacBook directly.
5. Press Apply when calibration succeeds. Applying a valid calibration turns Power on automatically.

Stop ends sounds that are playing or pending without changing Power. If Guard turns Power off after very rapid repeated output, lower the speaker volume and turn Power on again.

Trial and licence

The three-day trial starts only after you confirm Start trial & Power on and DeskTap completes its first successful Power On. It includes all nine built-in packs, with up to 100 actually audible outputs per pack. Custom sample loading requires activation.

Activation requires the Polar purchase email, the complete Polar licence key and internet access. One Mac can be active at a time. A successful validation allows up to 72 hours of offline use. Deactivate the current Mac from the Polar customer portal before moving the licence to another Mac.

Custom sample packs

Activated users can load one folder containing 1–78 supported top-level audio files or one .desktappack. Supported formats are WAV, AIFF/AIF, FLAC, MP3 and M4A. DeskTap checks the whole pack before replacing the current pack and never modifies source files.

Pack limits are 10 seconds per sample, 240 seconds total, 16 MB per source file, 192 MB total folder source audio, 128 MB per .desktappack and 128 MB normalized audio in memory. Sources must be mono or stereo at 8–96 kHz. WAV/AIFF must be 16-, 24- or 32-bit.

Troubleshooting

Reporting a problem

Include the DeskTap version and build commit shown in About, Mac model, macOS version, desk material and placement, audio settings, calibration state and short reproduction steps. Never post the licence key publicly.

Refund help

If DeskTap does not function on a system disclosed as supported at purchase, email contact@gridwavedsp.com and we will help troubleshoot it. If the issue cannot be resolved, we will arrange a refund through Polar. Include the purchase email or Polar order reference and the problem-report details above. We may ask for a short video or other diagnostic detail when reasonably needed. Do not send the complete licence key unless support provides a secure reason and route.

Physical damage caused by tapping, excessive force, repeated high-energy impacts, hard objects, drops, unstable placement or vibration is not a software functionality issue and does not by itself qualify for a refund under this voluntary policy. Applicable statutory rights and non-excludable remedies are not limited. See the DeskTap Refund Policy Version 1.0 for the complete terms that accompanied this archived support document.
