Accessories

TRS Port

The Smart Multibox has a 1/4-inch TRS input, which can be used to connect an expression pedal, a 1-button footswitch or 2-button footswitch, and scripts can act based on changes to the connected accessory.

Please see the Hardware Access Functions and Callbacks sections to find out how to write scripts using these accessories.

Expression Pedal

The Smart Multibox accepts a standard tip-to-wiper expression pedal. This is the most common kind, made by Roland/Boss, Mission Engineering, Fractal Audio, etc. 

NOTE: This is different than all the older RJM Music products. We formerly used the other type of expression pedal, ring-to-wiper, but we're starting to move to the more common format, starting with this product.

For best results, use an expression pedal with a 10k or 25k linear pot. Higher resistances may result in not getting the full range of values.

External Switch

The TRS port can also be used to control a 1 or 2 button footswitch. The footswitch should be a simple momentary or latching switch, with no LED in series with the switch. A 1 button footswitch can use a 1/4-inch TS (mono) cable, but please note that the ring switch will always be considered "on" when using a mono cable. When using a 2-button footswitch, a 1/4-inch TRS cable is required.
