If you are lucky enough to own a Roland Jupiter-6, you already know how distinctive it is. It’s a powerful and characterful instrument, but also one that has often been misunderstood and under-integrated in modern workflows.

One of the main reasons is its very limited original MIDI implementation and its reliance on cassette-based patch storage, which meant the Jupiter-6 never developed a strong patch-sharing culture or deep integration with contemporary production systems.

Over the years, a small number of modifications have attempted to address these limitations. The Europa Mod was the most extensive, but it is no longer available or actively supported. The currently maintained and widely adopted solution is the Tauntek MIDI Mod, which is far less invasive and adds robust, reliable MIDI functionality to the Jupiter-6.

Building on the capabilities introduced by the Tauntek Mod, we have developed Deep Edit — a browser-based editor, librarian, and sequencer designed to take the Jupiter-6 significantly further into modern production and performance contexts.

Deep Edit is in active development, but it is fully usable today, with all core functionality working as intended. A detailed help section is available within the editor; what follows is a high-level overview of its design and capabilities.

Dual-Panel Editing & Sequencing

Deep Edit is designed around the Jupiter-6’s dual-panel architecture, treating each panel as an independent but tightly integrated instrument.

• Each panel can be edited independently via dedicated on-screen panels
• Each panel has its own polyphonic step sequencer
• Sequencers can run independently or in coordination for complex layered patterns

This approach allows the Jupiter-6 to function as a far more flexible performance instrument than its original design allowed.

Integrated Memory & SysEx Management

The Jupiter-6’s internal memory system is fully integrated into Deep Edit’s sequencer and memory manager.

• SysEx dumps can be received directly from the Jupiter-6
• Patches can be stored, recalled, and resent at any time
• Memory changes can be triggered per pattern or per step

This enables performances where patch changes are an active part of sequencing, rather than a static setup task.

Patch Library & Sharing

Very little exists online in terms of shared Jupiter-6 patches. Deep Edit addresses this with a built-in Patch Library designed specifically for Tauntek-modified Jupiter-6 systems.

• Save and manage your own patches
• Send patches to either panel, or both
• A small factory patch set is included for demonstration purposes

Once patches are created, they can be stored on the Jupiter-6 itself and recalled automatically as part of sequenced performances.

Patch Generator with Seed Management

Deep Edit includes a patch generator with a unique seed-based workflow.

• Generate patches by category using built-in seeds
• Control how much parameter variation is applied
• If you create a sound you like, it can be saved as a new seed
• Future patch generation can then be based on your own sounds

This allows exploratory sound design while still keeping results grounded in musically useful territory.

Advanced Sequencing & Automation

Each panel includes a two-lane step sequencer with deep automation support:

• Record automation from external MIDI controllers (using the MIDI CCs documented in the Sunshine Jones reference guide)
• Record automation directly by moving on-screen controls
• Generate random monophonic sequences
• Record polyphonic MIDI note input
• Trigger different Jupiter-6 memory locations per step (AFX-style patterns, particularly effective for percussive sounds)
• In this release, step length is set, so recorded notes are locked to the step, so you would need to use longer envelope release to hold notes. You could consider this a bug or a feature depending on what style of music you are looking to make with it. This approach lends itself well to a lot of electronic music production.

All automation data can be edited at the step level, making Deep Edit suitable for both structured composition and live performance.

Deep Edit is intended to give the Jupiter-6 the editor, librarian, and sequencing depth it never originally had, while respecting the character and architecture that make it unique.

It only works with Tauntek modified Jupiter 6’s and is designed to be used on the desktop, not mobile (mouse control required) with modern browsers such as Chrome or Edge which have midi support.

Deep Edit is offered free to use, with no implication of support.
