Synth Patch Sysex Message Formats

For best results, we recommend using Circuit’s USB connection for SysEx communication, as it is faster and more reliable. Although Circuit will receive SysEx messages via MIDI DIN, any response will be sent via USB only.

Replace Current Patch

This table describes the format of the “Replace current patch” message.

When this is received by Circuit it replaces the contents of the current sound (in RAM) for the specified Synth part.

There are states in which the device is not capable of receiving this message. For example, it may be busy processing another sysex message. In these situations the message will be ignored. The message may be sent without delays between the bytes. However, consecutive messages should have at least 20 ms between them to allow time for processing.

350 bytes in total

Replace Patch

This table describes the format of the “Replace Patch” message.

When this is received by Circuit it replaces the contents of the specified patch in Flash memory.

Current Patch Dump Request

This table describes the format of the “Current Patch Dump Request” message. There are states in which the device is not capable of receiving this message. For example, it may be busy processing another sysex message. In these situations the message will be ignored. The message may be sent without delays between the bytes. However, consecutive messages should have at least 20 ms between them to allow time for processing.

When this message is received on either MIDI DIN or MIDI USB, Circuit will respond by sending a Replace Current Patch message to its USB port. The location in the response will match the location in the request, and the patch data will correspond accordingly.

9 bytes in total

Patch Dump Request

To obtain a patch from Flash memory, follow these steps:

First send a Program Change message with the desired patch number (0 – 63) to a synth MIDI channel.
Wait enough time for the patch to load from Flash memory (10 ms should be plenty)
Send a Current Patch Dump Request message with the Location set to the corresponding Synth part.

Consecutive sequences should have at least 20 ms between them to allow time for processing.

Format of a Synth Patch (Single) SysEx File

To create a single patch in a portable format that can be shared with others, use a sysex file containing a single “Replace Current Patch” sysex message with the Location set to Synth 1.

Format of a Synth Patch (Bank) Sysex File

To create an entire bank of 64 synth patches, use a sysex file containing a concatenation of 64 separate “Replace Patch” sysex messages. Each message should overwrite consecutive patch numbers, starting from 0 and counting up to 63.
