help Roland A-33 FAQ

Does the Roland A-33 have 61 keys?

No. The Roland A-33 is a 76-key MIDI controller with a semi-weighted, velocity-sensitive keyboard, so the catalog description should not call it a 61-key model. [Sweetwater specifications](https://www.sweetwater.com/sweetcare/articles/roland-33-technical-specifications/)

Can the Roland A-33 split its keyboard into two zones?

Yes. Its Upper and Lower zones can transmit on separate MIDI channels, allowing you to control two external sounds from different parts of the keyboard. [Roland support](https://support.roland.com/hc/en-us/articles/201918839-A-33-Setting-the-MIDI-Transmit-Channels)

Can the Roland A-33 control hardware synthesizers without a computer?

Yes. The rear panel includes MIDI In, MIDI Out 1, MIDI Out 2, and MIDI Thru connections for external MIDI equipment. It is an older hardware MIDI controller rather than a modern USB-only keyboard.

What does aftertouch do on the Roland A-33?

Aftertouch lets you send additional MIDI expression by pressing a key more firmly after the initial note. On the A-33, aftertouch can be assigned through the combined bender, modulation, and aftertouch lever.
