Mela 7.5 introduces MIDI Echo, a new MIDI processor with a customisable feedback path. Each repeated MIDI event is sent through the Echo Path sublane, where it can be processed by submodules before being fed back into the next repeat. Repeats are tracked by MIDI channel, support up to 16 echoes, and can be timed in seconds or with tempo-synced values.

MIDI Delay, MIDI Channel, and MIDI Source were also improved to work well with MIDI Echo and make sophisticated MIDI delay effects easier to build. For example, inserting MIDI Channel in Modify mode within the Echo Path can produce infinite repeats, while MIDI Source can now convert MIDI channels 1 to 16 into a Mod signal, allowing each repeat to have different parameter settings.

This video highlights the new MIDI Echo module introduced in Mela 7.5. It shows how its customisable feedback path sublane can recreate Note Echo-style behaviour and go beyond.

This video explains how MIDI Echo works, including how it uses MIDI channel numbers to track repeats. It also demonstrates how the MIDI Channel module can be used to create infinite repeats.

Mela 7.5: MIDI Echo Part 3 - Modulate Feedback Path

This video demonstrates how the MIDI channel number used for event tracking in the feedback path can be repurposed as a modulation source using the MIDI Source module. It also shows how the Mod Steps module can map channel numbers to precise Mod signal values.

Mela 7.5 Changelog

MIDI Echo

• The MIDI Echo module repeats incoming MIDI events using a customisable feedback path.
• The Echo Path sublane receives each repeated MIDI event for processing.
• Repeats are tracked using MIDI channel numbers.
• It supports up to 16 repeats.
• The interval between repeats can be set in seconds or using tempo-synced values.
• While the module is optimised to avoid stuck notes or infinite repeats during normal use, it can still be pushed creatively.
• For example, inserting a MIDI Channel module in Modify mode within the sublane can produce infinite repeats.
• In such cases, the Panic action is available in the module actions menu.
• The module also includes an indicator for when the echo buffer is full.
• MIDI Echo is a Mela Lab module and part of Collection 5.

Other Changes

• Mod Steps: The Retrig parameter has been renamed to Trigger, adding a new behaviour where, in Step mode, the sequencer advances to the next step on note-on.
• MIDI Delay: Redesigned the module UI.
• MIDI Delay: Renamed the Mode parameter to Sync and added tempo-synced options 1/64 and 1/128.
• MIDI Delay: Fixed an issue where modulating delay time could cause some MIDI events to be delayed by an incorrect amount.
• MIDI Delay: Fixed an issue where changing the On parameter state while processing notes could cause stuck notes or orphaned note-offs.
• MIDI Channel: Fixed an issue where changing parameters while processing notes could cause stuck notes or orphaned note-offs.
• MIDI Channel: The Channel parameter is now controlled with a dial instead of a pop-up list.
• MIDI Source: The new Channel Number source option maps MIDI channels 1 to 16 to a stepped [0%, 93.75%] Mod signal.
• Digital Delay: Added an indicator to show when the built-in clipper is active.
• Signal Indicators: Updated Feedback’s clip and Note Pulse’s pulse indicators to match the style of Digital Delay’s clip indicator.
• Parameters: In the parameter actions menu, the presets section is now labelled. Parameter presets appear under Presets, while list and toggle parameters use Values.
• Factory Presets: Added the “Euclid Sequencer” preset to the Parts group. It uses Euclid to generate rhythm and Mod Steps to provide the notes.
• Presets: Fixed a crash caused by a malformed preset with a Root Stack submodule that’s not a Group type.
