Akai Professional MPX16chat_bubble_outlineFrom real comments

The device offers only one bank of 16 custom sounds with no way to switch pages or scenes live; changing kits requires a slow reload from the SD card.

@ShanesQueenSite

I have the MPX8 and in retrospect I probably should have bought the 16 - the reason is that I thought the MPX product would allow you to have different pages or scenes ... it does not. There is only 1 bank of 16 custom sounds available for you to program. But overall I'm happy with the product performance , apart from a very slow loading of the data from the SD card, but if you start it before your set, you can have it all ready in time for the performance.launch

@bassnotestudios

Does this have multiple banks or will I need to reload every single time I need to change something? My main use for this right now is only pre recorded voice lines. Any suggestions?launch

@johnnyguitar7921

can you change \"kits\" in Real Time? suppose i have 16 assigned PADS, is there a switch to change to the other 16 PADS with different sammples? or are they gonna have to \"load\" again from the SD card, taking loads of time..?launch

What you can't do with the MPX16: You can't change the MIDI channel, it's fixed to channel 1 in & out. You can't organize your samples on the SD-card, all samples MUST be in the root directory. You can't put more than 512 samples in the root directory, otherwise the SD-card won't be recognized. You can't switch the samples while playing, because of the long time to load samples.\n\nDon't expect too much from this device ...launch

Users report SD card recognition and format errors even on properly formatted FAT32 cards, 'file too big' errors on files within stated limits, and crashes or freezing when deleting samples.

I get SD card error even though my SD card is formatted to fat32. Bad product.launch

i have problems with bigger files.. even tho the files are into the max size and format. I am talking about files less than 50mb (2 minutes voice samplers)... marks \"file too big\" and wont load.. even tho i already have few big files. I am going crazelaunch

INFURIATING..... I wanted this to be such a good machine but it keeps crashing and flashing format problems with sd card....... It doesn't save anything to pads every time you switch off you have to start loading samples to pads all over again....... Refuses to delete samples it's just freezes.... HORRIBLE!!!!\n It's the kind of hardware that makes me want a daw 😖😖😖launch

Multiple users confirm the MPX16 receives and sends only on fixed MIDI channels (varying by firmware version), preventing use of multiple units for independent live sequencing.

@kiskadar69

The MIDI handling of the Akai MPX16 depends on the firmware version.\n\r\nfw v1.0.7 (not available for download from Akai website):\r\nreceive on all MIDI channels (=Omni), send on MIDI channel 10.\r\n\r\nfw v1.0.18 (2015?, no longer available for download from the Akai website):\r\nOnly receives on MIDI channel 1, send on MIDI channel 10. Probably cannot handle MIDI messages received with Running Status. \r\n\"The MPX16 will now receive on MIDI channel 1, and send on MIDI channel 10. It now reboots/resets on a regular basis when used in a MIDI setup.\"(Brian Lewis)\r\n\"With MIDI Running Status off, so far I can send the MPX16 a huge amount of MIDI information without the reboot problem.\"(Joseph Place)\r\n\r\nfw v1.0.19 (made on 25 August 2015, released on 17 May 2016, downloadable from the Akai website):\r\nReceived on DIN MIDI In (channel 1 only): handles MIDI messages sent with Running Status. Note On (90H nnH vvH, where vv=01..7F, the volume is always determined by the velocity received, even if the pad velocity is set to Off), Note Off (80H nnH vvH). After loading a kit, the MPX16 by default incorrectly handles \"90H nnH 00H\" messages (for example, the Roland A-33 sends such a message when a key is released): for Hold and Loop pads, playback does not stop immediately, but plays the sound sample to the end. First solution: after each kit load, press one of the pads of the MPX16. Second solution: after each kit load, send an 80H nnH vvH message to the MPX16. Program Change messages: no reply. CC7 messages: no reply.\r\nSend to DIN MIDI Out (channel 10 only): always sends with status byte (=Running Status is not used). Note On (99H nnH vvH, where vv=01..7F. If pad velocity is set to Off, then vv=7F), Poly Aftertouch (A9H nnH ppH), Note Off (89H nnH vvH, with release velocity. If pad velocity is set to Off, then vv=7F). Program Change messages: does not send. Active Sensing messages: does not send.\nSoft Thru: no.\r\nUSB: receives like DIN MIDI In (=channel 1 only) and sends like DIN MIDI Out (=channel 10 only), but also receives Program Change messages on channel 1. Program Change 1 (C0H 00H) and Program Change 11..128 (C0H 0AH .. C0H 7FH) messages cause the MPX16 to load the i01 kit. Program Change 2..10 (C0H 01H .. C0H 09H) messages cause the MPX16 to load the corresponding internal kit (i02..i10).launch

@NovaDetour

Hello, Can anyone say whether the MPX16 is really (still) stuck on only one MIDI channel? I'd like to use three MPX16's for live sequencing with the multiple stereo outs but that's a dead issue if they only fire off the same MIDI channel. Nothing can be found about MIDI channel selection in Akai's downloadable user guide. >>> TYVM !launch

Several users report that assigned pad sounds don't persist after switching the unit off, forcing them to reload samples every time they power it on.

@skaniv

How save a sound when he is in the pad because when i switch of MPX16 and i switch on, all sound don t save and restart in the begininglaunch

Do you need to assign sound effects to the pads every time you turn the unit on? I haven't been able to figure out a way to save themlaunch

Loading samples or kits from the SD card can take up to a minute, and one reviewer noted a noticeable half-second latency when triggering a pad, making live performance risky without pre-loading.

@ShanesQueenSite

I have the MPX8 and in retrospect I probably should have bought the 16 - the reason is that I thought the MPX product would allow you to have different pages or scenes ... it does not. There is only 1 bank of 16 custom sounds available for you to program.

@TrucNguyen-og6vh

hi Daniel, do you experience a latency problem when assign a sample to the trigger pad from SD card? I have seen at least 0.5 sec delay when I hit the trigger pad. This is crazy. That's means I can't play live performance with band.launch

Multiple commenters struggle to figure out basic tasks like formatting the SD card or loading custom samples, and say tutorials only praise the device without explaining how to actually use it.

@delilablack5921

Can't find any tutorials that actually show HOW to use your own samples on this. They just keep saying how great it is. but how do you do it?launch

@barronmarshall2331

thank for the video. I just saw it in my suggestions. I own this item but like marko v below I find this very hard to figure out. it does sound great and the pads respond well. however I haven't been able to figure out how to format the sd card so I can record my samples. I am glad you showed how to use the converter, as I did not understand this until you showed it. I thought formatting the card would be similar to using the roland sp 404 sx. thanks again.launch

Users ask about changing tempo or pitch of a loop or syncing to an external clock, but comments indicate these features aren't available on the MPX16.

Two users report that recorded loops or samples lose their beginning or attack, with sound seeming muffled or missing right at the start of playback.

@verslebleu

Hello,\nWhen I create a rhythmic loop and load it into the MPX16 the sound seems to drop or become muffled right at the beginning of the loop. It’s as if the attack is being cut or reduced.\nHow can I fix this issue with the attack at the start of the loop?launch
