Newbie with a specific Use Case regarding midi and Alesis

[thenewdrummer]

Edrumin midi out >Nitro midi in, Nitro USB disconnected = Edrumin triggers Nitro's internal sounds.
From memory in this scenario the Edrumin's midi isn't passed through to the Nitro's midi out.
Short answer - with your pc off you can trigger your Nitro sounds from your edrumin.

Thanks for the information
