SP-404MKII firmware 5.50 introduces side-chain compression and exFAT

SP-404MKII firmware 5.50 adds side chain compression and exFAT SD compatibility, introducing two significant enhancements to the SP-404MKII unit.

Live side-chain signal processing is now available directly on the unit as part of the side-chain compression feature. Routing options for SOURCE and TARGET now allow selecting DRY in addition to BUS 1, 2, 3, and 4, and the GAIN parameter is specified as makeup gain with a range from 0 to 6 dB.

The firmware update also identifies exFAT as the preferred interchange format between Windows and macOS and notes that exFAT additionally works on Linux with some enabling support.

Firmware version 5.50 for the SP-404MKII adds side chain compression. Live side-chain signal processing is now available directly on the SP-404MKII unit. The firmware update explicitly provides this live side-chain capability as part of the version 5.50 feature set. The release is described in the article as bringing two long-awaited features.

“SP-404MKII version 5.50 brings two long-awaited features — side chain compression and exFAT SD compatibility.”

“Live side-chain signal processing is finally available directly on the unit.”

“For SOURCE and TARGET, you can choose DRY in addition to BUS 1, 2, 3, and 4.”

“GAIN is basically makeup gain (from 0 – 6 dB).”

“exFAT is now the preferred interchange format between Windows and macOS. (It even works nicely on Linux, though you may need to enable it.)”

SP-404MKII firmware 5.50 adds side chain compression and exFAT SD compatibility

Firmware version 5.50 introduces exFAT SD card compatibility for the SP-404MKII unit alongside the side chain compression feature included in the same update. The release identifies exFAT as the preferred interchange format between Windows and macOS, stating that exFAT is the recommended filesystem for cross-platform transfer. The update further notes that exFAT also works on Linux, with the caveat that enabling may be required for Linux environments. The exFAT compatibility described in the firmware applies specifically to SD cards used with the SP-404MKII, allowing the unit to recognize and operate with exFAT-formatted SD media.

Side chain compression functionality — SP-404MKII firmware 5.50 adds side chain compression and exFAT SD compatibility

SP-404MKII firmware 5.50 adds side chain compression to the SP-404MKII unit, identifying side chain compression as one of the significant features introduced in this firmware release. Live side-chain signal processing is now available directly on the SP-404MKII unit, enabling the unit to perform side-chain processing in real time as part of the version 5.50 feature set. For SOURCE and TARGET routing selections, the firmware explicitly allows choosing DRY in addition to BUS 1, BUS 2, BUS 3, and BUS 4. The GAIN parameter within the side chain compression function is described as makeup gain with a numerical range from 0 to 6 dB, specified in the firmware information for version 5.50. These statements together describe the side chain compression functionality provided by firmware version 5.50 for the SP-404MKII. The firmware release pairs exFAT SD compatibility with side chain compression as two features introduced in version 5.50.

Side chain compression — SP-404MKII firmware 5.50 adds side chain compression and exFAT SD compatibility

SP-404MKII firmware 5.50 adds side chain compression to the SP-404MKII unit, listing side chain compression as a primary feature introduced in this firmware release. Live side-chain signal processing is now available directly on the SP-404MKII unit, providing on-device processing capabilities described as live in the firmware information for version 5.50. The firmware release pairs side chain compression with exFAT SD compatibility as two features introduced in version 5.50.

For routing within the side chain compression function, the firmware explicitly allows selecting DRY for both SOURCE and TARGET in addition to BUS 1, BUS 2, BUS 3, and BUS 4, reflecting the selectable routing options documented for version 5.50. The GAIN parameter for the side chain compression is described as makeup gain and is specified with a numerical range from 0 to 6 dB in the firmware details for version 5.50, indicating the available makeup gain range. These routing selections and the GAIN parameter are presented in the firmware information for version 5.50 as elements of the new side chain compression functionality.

Firmware version 5.50 adds side chain compression and exFAT SD card compatibility for the SP-404MKII. The side chain compression feature provides live side‑chain signal processing directly on the unit, and the firmware explicitly lists routing options for SOURCE and TARGET that include selecting DRY in addition to BUS 1, BUS 2, BUS 3, and BUS 4.

The GAIN parameter associated with the side chain compression is described as makeup gain with a specified numerical range from 0 to 6 dB. The firmware also introduces exFAT compatibility for SD cards used with the SP-404MKII, identifying exFAT as the preferred interchange format between Windows and macOS and stating that exFAT works on Linux with enabling.
