Disaster Area Designs released beta firmware v19 / v25 for its Midi Pedals on January 20, 2026, according to the maker's beta change log¹. The release adds Expression Groups, a Bank Down MX option to the Strymon Bank command, and a delay control slider to the Strymon Bank command¹.

Expression Groups are described by the maker as "a new way to manage the expression inputs for MIDI Baby and Baby 3"¹. When adding expression pedal actions, users can select a Group number alongside the MIDI controller and channel values, and only items in the active Group are sent when the expression pedal is updated¹. A new Set Expression Group action sets the active group, and MIDI Baby 3 devices have separate Groups for each expression pedal input¹. The maker notes that a "blank" group with no assigned members disables all expression pedal actions, and that group settings can be combined with program selections so some presets carry different expression pedal functions¹.

On the Strymon side, the maker states that the BigSky MX has a slightly different command structure and will not work with its existing setup, which led to the Bank Down MX action and the new Delay slider in the editor¹. The maker's sample setup uses Bank Down MX for bank down with a 30ms delay and Bank Up for bank up with a 30ms delay, while the other large Strymon pedals work with the previous Bank Down command and the default 10ms delay¹.

Access to the beta features requires updating the device firmware to v19 / v35 and using the beta version of the MIDI Baby editor¹. A second beta, v19 / v35 BETA 2, followed on January 21, 2026, changing LED blinking during editor writes and altering slider behavior so updates are sent only on slider release¹. The same page also lists a later v21 / v37 update covering MIDI clock commands, including a new Set Tempo action¹. No price is given for the firmware¹.
