7 months ago - 7 months ago
The AM8104 replicates the Low Pass and High Pass Filters from the Roland Jupiter 4 analog polyphonic synthesizer, specifically using the Rohm BA6110 OTA chips found in early versions. This design, originally used in the 700 Modular System and later products like the System 100M and SH-2, features subtle component changes affecting sound character. The module includes a 24dB low pass filter and a single pole high pass filter, providing characteristic warmth and powerful resonance. High quality components, including polypropylene capacitors, are used throughout the filter circuitry. A keyboard follow feature enables the keyboard CV on the Doepfer bus to effect low pass filter frequency cutoff.

Frequently Asked Questions

Patcher aims to be the most comprehensive manager and database for modular gear, providing free access to public data. The project is open-source and available to everyone for free.

If panel images are missing for a module, you can upload them directly via the module’s detail page. Just navigate to the module page, and you’ll find the option to add images there.

Yes, partially. Export your rack as JSON from ModularGrid (requires a Unicorn account), then in the rack creator toggle "Import from ModularGrid" and upload that file. We'll match as many modules as possible and show you a preview split into confident, likely, ambiguous, and unmatched matches - you can resolve ambiguous ones manually before finishing the import. ModularGrid does not officially support this integration, so some modules may not match; you can always add those manually.

Use blank modules! Right-click on any module in your rack and select "Replace with blank" to create empty space. Blanks are available in all common sizes (1-20 HP for Eurorack, 1-26 HP for Intellijel). You can also add blank modules directly from the module browser - just search for "blank".
