MIDI Patch
This app acts as a MIDI message translator, converting incoming PC, CC, or Note On messages from Bluetooth devices into SysEx messages. It allows users to map controller inputs to control various MIDI-enabled hardware, such as guitar amps, by defining custom patches and message translations.
- MIDI message translation (PC/CC/Note On to SysEx)
- Unlimited user-defined patches
- Customizable inbound and outbound message mapping
- Value translation options (toggle, min/max)
- User-defined devices and functions
- Automatic patch saving and file backup/restore
- Bluetooth MIDI device discovery

MIDI Patch is a MIDI enabled App that listens for and processes inbound PC, CC or Note On MIDI messages received from bluetooth MIDI devices/apps and translates these messages to SysEx MIDI messages, which are relayed/sent outbound to connected bluetooth MIDI devices/apps based. The App is essentially a relay/broker and translator of MIDI messages from PC/CC/Note On to SysEx MIDI messages. The App will listen and send to any MIDI bluetooth devices or MIDI enabled apps connected to the iPad or iPhone. While use cases can be wide and vary based on specific user requirements, the typical use of MIDI Patch would consist of mapping inbound messages from MIDI enabled foot controllers capable of sending PC, CC or Note On MIDI messages and generate SysEx MIDI messages intended for devices such as guitar amps, allowing use of generic MIDI foot controllers or MIDI apps to adjust guitar amp settings that support/expect SysEx messages. The app includes in-app configuration for specific guitar amps (Boss Waza Air, Katana Air, Katana Air EX, Katana GO, Katana MkII, Katana Gen3, Pocket GT, Valeton GP-5 and GP-50) but can also be configured for any MIDI device or App that expects/receives SysEx messages. Each patch is user defined based on specifying the inbound message to listen for (PC, CC or Note On) and configure the translation of this message to an outbound SysEx message by specifying a device, a function (either using in-app configured devices/functions or user defined ones) and the value logic to apply (specific value or received value with optional value translation such as Toggle and Minimum/Maximum clamping). Specific features include: - Unlimited user defined patches consisting of inbound and outbound message configuration. - Support for both PC, CC, Note On inbound messages (will listen for either PC, CC or Note On). - Each patch will translate/build the outbound SysEx message by selecting a Device, Function, and Source of Value handling. - The Source of Value can be set to Specific Value (send a constant value each each time the patch is invoked) or Received Value (will send the received CC code value). - Additional Value Translation is available for the Received Value scenario including Toggle (0=0/OFF and 1-127=1/ON) or Minimum/Maximum (received value will be converted to a value within a set minimum and maximum value). - User defined Devices and Functions can be created and become available for use in defined patches. - Patch configuration is automatically saved between sessions and can also be backed and restored to/from file. - A bluetooth device discovery page is available from within the app (to view/select the connection state of Bluetooth MIDI devices). IMPORTANT: This app includes configuration which works with some of the current Boss amps and Valeton pedals, with no guarantee of compatibility with future firmware releases.

Verdict
The clearest difference is price: Audiobus at Free against MIDI Patch's $9.99. Audiobus also leads on ratings volume (593 vs 3) and iOS requirement (13.0 vs 15.0). MIDI Patch's advantage is rating (5.0 vs 4.5) and in-app purchases (none vs 11). On update cadence, ads and device support there is nothing between them.
