What the checker does
MIDI Roundtrip Check reports structural differences and heuristic warnings. It does not guarantee how every synthesizer, DAW, or device will sound. Keep source files and confirm critical exports by listening.
Purchase
Receipt mode is a one-time license for one person across their own devices. Sociobot/Dodo is the merchant of record. Checkout, tax, and refunds are handled there; a refund revokes the license.
Acceptable use
You may inspect files you have the right to use. Do not use the service to violate law or others’ rights.
Warranty and liability
The software is provided “as is,” without warranty, to the extent permitted by law. We are not liable for lost work or downstream playback decisions.
