- Alesis releases the Kitstream, a module that attaches to your bass drum hoop to record and stream your acoustic drum kit.
- A built-in stereo microphone captures the whole kit, while a trigger converts each bass drum hit into a MIDI note.
- A single USB-C cable sends audio and MIDI to your computer, and the module can also record on its own, with up to 50 hours of internal memory.
- Itâs useful both for the beginner drummer who wants to listen back and the teacher who films their lessons, with 500 sounds and sample import for hybrid playing.
We know Alesis primarily for their electronic drums: the Strike and Strata ranges are among their key references. With the Alesis Kitstream, the brand turns this time to acoustic drums, letting them sound as they do, including heads, shells, and cymbals.
The box combines what usually requires several devices: a stereo microphone, a bass drum trigger, a sound module, and a USB-C audio and MIDI connection. It clamps onto the hoop, a calibration assistant adjusts the response to your playing, and recording can start. Capturing your drums in seconds: thatâs Alesisâs promise, and the whole design of the module revolves around it.
The Kitstream attaches to the bass drum hoop thanks to its dedicated clamp, included in the box. On the drummerâs side, four knobs control the mic level, trigger, reverb, and effects.
An LCD screen and a row of buttons (kit, settings, click, recording, save) complete the front panel. Everything is adjustable from the seat, sticks in hand, without leaving the kit to touch a computer.

How the Alesis Kitstream captures an acoustic drum kit
Placed on the bass drum, the Kitstream sits at the center of the kit. Its stereo microphone captures the overall image of the drums: the impact of the bass drum, the snap of the snare, the presence of the toms, and the openness of the cymbals. The result is a direct and coherent capture, the kind you hear sitting behind the drums.
This type of capture is well suited for demos, videos, rehearsals, and headphone work. The sound is already balanced by the mic position, and the front panel controls serve to adjust it rather than build it from scratch.
In the same box, the built-in trigger detects hits on the bass drum. The automatic calibration assistant adapts its response to your playing style, so the module recognizes your hits from the first session.
A trigger is a sensor that reacts to the vibration of a drum. It does not transmit sound: it signals that a hit was played, and with what force. The module translates this signal into a MIDI note, a digital message that any sound can then use.
A mic input to complement the capture
A dynamic mic input allows you to add a source depending on the context. An additional drum mic on the snare or bass drum, an overhead above the cymbals, or a voice to comment on what you play. This signal goes directly to the moduleâs mix, without an intermediate step.
Hybrid playing without changing drums
The trigger opens the door to a hybrid setup: the acoustic kit remains central, and electronic sounds are added. Each bass drum hit can trigger the Kitstreamâs internal sounds or a virtual instrument via MIDI. You can reinforce the attack, add an electronic layer under the natural sound, or completely change the character of your bass drum.
The library includes 500 sounds of drums and percussion, organized in 50 kits, from realistic timbres to more modern textures. Behind that, 13 reverbs, 26 effects, compression, and an equalizer shape the sound without leaving the module. A dry kit gains depth, a bass drum gains presence, and the whole fits into a mix ready to share.
Sample import takes customization further: up to 99 WAV files at 44.1 kHz / 16-bit. An 808-style sub kick, common in hip-hop and pop, can thus double your acoustic bass drum on every kick hit.
The module finally supports up to 6 external pads or triggers. An electronic pad placed next to the hi-hat, a trigger stuck on the snare drum: the setup grows at your own pace, piece by piece.
Start the automatic calibration by playing as you really play, at your rehearsal dynamic. Itâs that hit the trigger needs to learn to recognize, not a held-back strike played just for the setup.
Recording and streaming daily with the Alesis Kitstream
Connected to a computer
Connected via USB-C to a computer or compatible device, the Kitstream transmits both audio and MIDI simultaneously. It then acts as an audio interface for your drum kit: the stereo output goes to your production software, and the bass drum notes too, all on the same cable.
Itâs the same connection for live streaming. The kitâs sound, effects, and any vocals arrive already mixed in the streaming software, ready to go live.
Without a computer
The module can also record on its own. Its internal memory holds up to 50 hours of content, with takes up to 60 minutes maximum. Each practice session leaves a trace, and you can listen back a week later to check if that snare groove really keeps the tempo.
The click button starts a metronome, and two headphone outputs (6.35 mm jack and 3.5 mm jack) work in parallel. In a private lesson, the teacher and student each plug in their studio headphones and hear the same thing. An auxiliary input and Bluetooth connection complete the connectivity to bring in an external source.
Best uses
Alesis targets drummers from beginner to advanced, whatever the style: pop, rock, funk, gospel, electro, or metal. The situations where the Kitstream is useful are numerous:
- Track your progress by recording yourself at every session, with no setup needed.
- Shoot demo videos with your voice as commentary on the mic input.
- Give or take an online lesson, drums and voice in the same stream.
- Keep a groove idea as a demo for the band, before rehearsal.
For a first setup, start with just the stereo mic and the trigger. Find your balance between acoustic sound, reverb, and effects, then add a mic on the dynamic input or a first external pad when you need it.
FAQ - Alesis Kitstream
Do you need a computer to record with the Kitstream?
No. The module records internally up to 50 hours of content, with takes up to 60 minutes maximum. The computer is used when you want to work in production software or stream live, via the USB-C cable.
How do you install the Kitstream on the drum kit?
It attaches to the bass drum hoop with the dedicated clamp, included. An automatic calibration assistant then adapts the trigger response to your playing.
Can you add a mic to the Kitstream?
Yes, thanks to its dynamic mic input. You can plug in a bass drum or snare mic, an overhead, or a vocal mic. The signal goes straight to the moduleâs mix.
Does the Kitstream control a virtual drum kit?
Yes. The trigger converts bass drum hits to MIDI, sent over USB-C with the audio. It can then trigger a virtual instrument in your software.
Can you load your own sounds into the Kitstream?
Yes, up to 99 WAV files at 44.1 kHz / 16 bits. They add to the 500 internal sounds, and the module supports up to 6 external pads or triggers to play them.
An acoustic drum kit ready to record
The Kitstream starts from a simple observation: the best time to record is when youâre already sitting behind the kit. One clamp, one calibration, one cable, and your acoustic drum kit becomes a source ready for video, streaming, or a demo. And when the desire for hybrid grows, the samples, MIDI, and pad inputs are already there, on your bass drum hoop.
