Can I create 50 mins of no beats on the MPC one +

Long situation short. I have 50 min recording on an ancient handheld digital recorder. For technical reasons and damage, this recording can only be taken off the recorder by sending the audio out through the headphone jack on the device. It will play it, but I can't send it file-wise.
I want to hook up the old device to MPC one + and send 50 mins of old precious audio into 3 samples of 16 mins, 16 mins, and 18mins. Then, combine them into one 50-minute project. Is this possible? No drums, no disco-pop, no fun of any kind, just a recording of someone talking. Can the MPC one + allow me to combine the samples into a continuous recording? Or even allow me to convert the samples into one 50-minute WAV file? I have no other line in jacked device. It is best to assume I am in a blank room with the MPC one + an old busted 2001 DM-1 handheld, and any chord you can imagine, but nothing else.

I'd try that with a computer and a recording program such as Audacity.

It may be doable, but only just. And it will all be in the MPC's RAM until you save the project, so if it crashes before saving, nothing will be on your disk yet and you'll have to re-record.

Mpc one can hold up to around 50 minutes of stereo audio, audio tracks limited to 5 minutes each, but the sampler can go for 20 mins per sample. But basically an mpc is not the tool for this job, if you don’t have access to a computer I suspect you could even use a phone for this

This is a job for the Force.

Put the MPC One + into controller mode, hook it up to your PC as your audio interface, install Audacity (it is free), and record the entire thing.

Or use an SP-404
Does it have to be recorded in one take?
If you only have the MPC to record on, I would suggest breaking it up into sections where possible then you may even be able to reassemble it after sampling. I assume it's a mixtape or similar and not something like a conversation?

Edit: just read the whole post! Just give it a go, I would. Once sampled you can then set up the samples to play at the specified time one after the other in the sequencer, which you can then press MENU select SAVE and then select AUDIO MIXDOWN. This will output the entire sequence as a stereo mix of the samples played in order. And voila, you have a 50 minute stereo wav file of your original recording.
