A musician has demonstrated the ability to run digital audio workstation (DAW) software, including Reaper, on an Android phone using an emulator called GameHub. The demonstration, posted online, showcases the potential to use a mobile device as a portable MIDI controller, though the process requires a high-complete smartphone processor – likely a Snapdragon 8 Gen 3 or better – to function smoothly.
The user reported that a Snapdragon 8 Gen 2 processor struggled to handle the processing load, even with a single note played. The current demonstration utilizes a phone with an 8 Elite processor, achieving stable performance with a buffer size of 256, resulting in approximately 49 milliseconds of latency. Audio crackling occurs with lower buffer settings.
Although routing MIDI directly to the Android device remains unresolved, the user is exploring methods to convert MIDI messages into keyboard keystrokes to control a virtual keyboard within the emulated environment. The demonstration was conducted without audio due to a conflict between the screen recorder and the audio driver, but the user confirmed functional sound within the DAW.
Software compatibility includes Ableton Live 11 and Reaper, with the emulator’s website also offering emulations of synthesizers such as the Waldorf Microwave, Virus B/C, and Nord Lead 2. The user also noted the emulator’s capability to run the game Red Dead Redemption 2 with high performance on their particular phone model.
The process of configuring an Android device as a MIDI controller involves activating developer mode by tapping the “Build number” setting seven times, then selecting MIDI as the default USB configuration. Apps like TouchDAW, MIDI Controller, and Wireless Mixer are available on the Google Play Store to facilitate this functionality, according to a guide published in August 2025. MIDI Commander is another app that can be used, requiring installation from bordero.it.
The feasibility of using an Android phone as a MIDI controller has been explored previously, with tutorials available on platforms like YouTube demonstrating connections to software like FL Studio. However, the recent demonstration highlights the advancements in mobile processing power enabling more complex DAW operation directly on the device.
