New gear arrives weekly, and most announcements are written for the general synth audience. If you play with per-note expression, you need different answers: does it receive MPE, does it send MPE, and what happens to pressure and slide on the way through? Here are five checks you can apply to any announcement, tested on products that appeared in the last week of October 2026.
Check 1: Does the post say "MPE" at all?
Start with the plain text. If a product supports MPE, the maker usually says so, because it is a selling point. Silence is informative.
Example: the Dreadbox Alecto, a two-voice analog percussion synth in 42HP Eurorack format, is triggered by buttons, an internal dual sequencer or an external trigger. It has no MIDI at all, so MPE is simply not applicable. That is not a flaw; it is a different kind of instrument.
Check 2: Is it MPE, polyphonic aftertouch, or something else?
These terms get mixed up. MPE assigns each note its own MIDI channel so that pitch bend, pressure and slide are per note. Polyphonic aftertouch sends pressure per key on one channel and does not carry per-note pitch bend or slide.
Example: Synth Anatomy reports that the Behringer Polykeys 61 is an open-source MIDI keyboard with polyphonic aftertouch. That is useful, but it is not the same as MPE. Compare it with Expressive E or Haken Audio instruments, which are designed around the full per-note model.
Check 3: Which direction does the support go?
"MPE support" can mean the product sends MPE, receives MPE, or both. A controller that sends MPE is only useful with a receiver that understands it.
Example: FabFilter Twin 3 update 3.10 is reported to bring MPE support to the subtractive synth. This is a receiving feature: you play it from an MPE controller. Check the release notes for which parameters respond to pressure and slide.
Check 4: What happens to channels along the signal path?
MPE breaks when something in the chain merges channels. Sequencers, MIDI-to-CV converters, hardware routers and some DAW tracks can all do it. Look for mentions of "MPE zones", "per-note channels" or "channel-per-note" in the manual.
Example: the Behringer BCR32 is a 32-encoder controller with a four-track sequencer and four CV/Gate outputs. CV/Gate is monophonic per output by nature, so per-note expression would need a different design. The announcement does not mention MPE, which is consistent with that.
Check 5: Is the feature shipping or promised?
Dates matter. A pre-order with a shipping date months away is not a tool you can use today.
Example: the Electra One Mk3 is a programmable controller with an 8-inch display, USB host and support for Ethernet RTP MIDI, OSC and MIDI 2.0. It is available for pre-order at 599€, with shipping reported to start in February 2027. The announcement does not mention MPE, and you cannot test it until it ships.
A quick scorecard
Run each product through this list:
- Does the maker use the word MPE?
- Is it MPE, polyphonic aftertouch, or channel aftertouch?
- Does it send, receive, or both?
- Is there anything in the chain that merges channels?
- Is it shipping today?
If you get five clear answers, you can plan with confidence. If you get two or three, hold off or ask the maker. Forums and manuals often answer faster than marketing pages.
Why this saves money
The most common frustration among newcomers is buying a controller that sends pressure, then finding a synth that ignores it. A two-minute check before purchase avoids that. For a broader introduction, see What is MPE?, and for official specifications visit the MIDI Association.
Announcements will keep coming. With these five checks, you can separate the instruments built for expression from the ones that merely sit near it.
