Whether navigating an array of instruments in the studio or hitting the stage with a multi-keyboard rig, managing your MIDI connections is not only essential to an uninhibited performance, but it can be tedious. Fortunately, Crumar’s 1U-sized GSi 5x5 Rackmount USB-MIDI Interface eliminates the hassle while providing ample opportunities for creatively integrating keyboards, controllers, grooveboxes, and anything else that can be managed via MIDI. Armed with 10 total 5-pin DIN MIDI ports — five inputs and five outputs — and a class-compliant USB-B 2.0 connector, the GSi is capable of deep interoperative integration with MIDI-controllable devices as well as direct compatibility with your computer, including Windows, MacOS, iOS, Android, and Linux operating systems. Studio scholars at Sweetwater appreciate the GSi’s form factor: robust metal housing not only protects sensitive circuitry, but it also keeps the interface in place without being weighed down by connected cables. What’s more, the included rack ears were ergonomically engineered to streamline cable management with its large cutouts.

Crumar GSi 5x5 Rackmount USB-MIDI Interface Features:

  • 1U rackmountable design means streamlined integration with most studio or stage racks without compromising real estate
  • 10 x 5-pin DIN MIDI ports provide a 5-in/5-out design for flexible MIDI management across compatible instruments and devices
  • Class-compliant USB-B 2.0 link allows for deep interoperative integration with computers for expanded instrumentation opportunities — no installation required
  • Flexible computer integration includes compatibility with virtually every operating system: Windows, MacOS, iOS, Android, & Linux (including AR Linux)
  • Additional Microsoft Windows driver is included for optional multi-client operation, letting you connect to multiple applications from the same MIDI port simultaneously
  • Rugged metal housing safeguards interior components while remaining sturdy enough not to be weighed down by connected cables
  • Precision-engineered rack ears (included) are designed with spacious cutouts for painless cable management with connected devices

Offer applies only to single-receipt qualifying purchases. Select manufacturers may require that only the manufacturer’s products qualify towards the minimum purchase amount needed to be eligible for promotional financing. Otherwise, an invoice that meets the minimum purchase amount and contains at least one qualifying manufacturer product is eligible for promotional financing. No interest will be charged on promo purchase balance, and equal monthly payments are required on promo purchase until it is paid in full. The payments equal the amount financed divided by the number of months in the promo period, rounded up to the next whole dollar. These payments may be higher than the payments that would be required if this purchase was a non-promo purchase. During the last month(s) of the promo period the required monthly payment may be reduced due to the prior months’ rounding. Regular account terms apply to non-promo purchases. New Accounts as of 07/31/2025: Purchase APR is 34.99%. Penalty APR is 39.99%. Min Interest Charge is $2. Existing cardholders: See your credit card agreement terms. Subject to credit approval.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
