Having issues with using AU and VST instruments. Using Korg Legacy (VST's) they will scan ok, however, once I start making a track, I get to track 3 and the software crashes. Using the M1 and Polystix VST. Once I get to track 3, click on the edit button to change sound, the sofware crashes. Using the latest versions of the VST.
The weird thing is ..... the AU instruments don't crash after track 3, only the VST's do


Also having an issue with Massive, Absynth and B4 (AU's). Will scan okay.
Once I pull the synth up to edit, when I hit a key on my controller, the note will continue to play even after I let it go. Using an MPK 61 controller USB'd to my computer.
The weird thing is .... the VST instruments don't hold notes once I press them, only the AU's do.

Also, attempted to use Sonivox Hip Hop Strings VST, while scanning, "fatal error" message comes up and crashes the software instantly. Had to remove that one completely.

Truly messes up the workflow trying to remember which ones will crash and which ones won't.

I know this has been touched upon before, but how likeley is it that the MPC Software should not be running on Snow Leopard at all? Anyone else experiencing something like this ?

Called Akai tech support today, on hold for too long after 3 tries.


Can you report the issues with any plugin you have in the following format in this thread:

Example:
1. Plugin Name: Halion
2. Manufacturer: Steinberg
3. Version: 1.0
4. OS platform: Win 7
5. Details about your specific issue: 'Authorization failed' message appears when scanning


I'll send it directly to the developers.

However, I am trying to make channels 15-16 (stereo pair) my Output Channels. I use these 2 channels as my main Output channels for everything coming out of my Mac.

When clicking on the Audio Test The signal does output on channels 15-16 as I wanted (all channels still selected), but will not play sequences at all. Nor, trigger audio from the samples on pads.

After some Q/A and frustration, I was able to get channels 1-2 on A&H ZED 16 as an Output for the MPC. All 16 channels are still selected on Preferences still, but sound is only coming out of channels 1-2. Weird.

As it stands, you are absolutely not able to de-select the other channels, and or just select channels 15-16 (stereo) as an Output.

I think I should be able to route the output to whatever channel I should want on my mixer. Kinda frustrating as I use channels 1-2, as post EQ's sends for 2 of my synthesizers.


So, I took some of the advice on here and upgraded my OS to Lion. However, the problem still persist. I am still not able to de-select channels on my A&H mixer within the MPC References section. When clicking on the test button I am getting a test tone on channels 1-2 & 15-16 now. However, audio from the MPC Ren is only transmitting on channels 1-2.

Tutor, I don't know that you will be able to reproduce the same problems. Unless you have an A&H, but this is clearly not right. For now I will settle for sound on channels 1-2. However, this is not ideal.

If you tap any pad CLEARLY during the metranome click in before recording has started, that pad will record at the very beginning when it actually starts to record. For example, if I Rec+Start, and say between the first count in click and the second (theres a total of 4) i tap my snare pad to make sure its the right one...after 4...when it actually starts recording, the snare will be recorded as if it was hit right upon the start of actually recording.

I dont think this is supposed to be this way. its definitely not like that on the 2000xl. Anyone else notice this?

came across these glitches that are reproducible (at least on mine so far). all are while trying to use the hardware exclusively...first, the particulars:

Osx 10.7.4, 8gb ram, dual quad Macpro tower, MPC 1.0 software

ISSUE 1
Deleting empty pgm field while Inst field set to plugin crashes program

Steps to reproduce:
a) on hardware, set a tracks 'Inst' field to 'plugin'
b) on hardware, in pgm field select a plugin
c) (optional, will crash wether this is done or not) record some midi notes
d) select the plugin name in the pgm field and press the 'window' button on the hardware
e) press delete, then' do it' to delete the plug in
f) while still in the pgm field, press the window button again, delete and 'do it'
g) program will crash
***note i stumbled on this while using the ren. this obviously is not a set of steps i would normally be doing, but inadvertantly doing the above sequence will take the progrsm down. i would think if the pgm field was empty then either the window button would not activate or at least the delete option would not appear so the exception could not be triggered.



ISSUE 2
Clearing a track from hardware results in 'Inst' field being set to 'mpc' while 'Pgm' field remains set to a plugin. Also, because of this, multiple instances of a plugin end up being created after each time a track is cleared. Prior instances are also unusable.

Steps to reproduce
A) create a track with a plugin instrument
b) (optional) record some midi data on the track
c) on the hardware, navigate to the track name, press the window button and select 'clear' and then 'do it'. The track will now show 'MPC' in the 'Inst' field, yet the 'PGM' field will still have the plugin active.
d) record some midi data. You will be able to hear the sounds from the plug in.
e) try to playback the midi data and you will now not hear the plugin because the midi data is actually routed to the MPC engine despite the plugin being displayed as the current program.
f) on the hardware, switch the 'INSt' field to plugin. the 'PGM' field will now go empty.
g) navigate to the PGM field and turn the jog wheel to select the same plugin instrument. observe the only option available will be 'duplicate'. select that option and another instance of the plugin will be created (observe that in the software under the project files you will see "plugin name-2")
h) in the software, click the plugin drop down for the track and attempt to select the original instance of the plugin and it will only create another instance of the plugin.

****note creating another instance of the plugin is not a problem in itself and I understand the need to instantiate another instance if creating a plugin on another track. The actual 'bug' or glitch is in steps a-c with regard to Inst showng MPC while PGM was still had the plugin active. I included steps d-h to illustrate the workflow implications. The problem above is that each time a track is cleared the user is ultimately forced to create a new instance for that track even though a plugin was already allocated to that track. The prior instances cannot be used and when you try (as was done above) it just creates yet another instance. I came across this because I had at one point 19 instances of a plugin sitting in the program list when looking at the software and I really only had that particular plugin used on one track...

Not sure what the correct behavior is supposed to be when a track clear is done on the Ren (meaning are only midi notes cleared or are both the Inst and Pgm fields supposed to be reset to default, etc..) but the current mismatch between the Inst showing MPC and the PGM being set to the plugin is a problem...

I will check on that Madbeats.

Here's something that caused my system 10.6.8 to freeze and crash, will test again later.

I had a sequence running on track 1 with "Chopped" samples on pads A1-A12, and drums on track 2.

I copied sample A1 to place on A13.

Went to Bank B to add the same sample to B1 (sequence playing whole time).

Pressed "Undo" and the software shut down and asked if I wanted to report to Apple.

The hardware stated that it lost communication, so I shut it off.

Turned hardware back on and re-launched software.

Software could not find hardware and said it would play silence (or something like that).

After numerous attempts hardware could not be found, I had to pull the usb from MPC to get things back in order.

Yes sir, same thing happening over here.

Forget the above, it did not happen during the test.

Go into the Preferences Menu. There you can set how you want to record. This is not a bug based upon what you described.


Edited - The recording of notes during count-in is a feature of the Ren. It is in Cubase 6and I believe an older MPC but can't recall exactly. I believe there was an option to turn it on/off but not in OS1. Will add a feature request for those users that don't like this behavior.

Confirmed bug and reported.


wakko1999 wrote:Issue 2 - Strange behavior with programs when moving from track to track on hardware

Not a bug.
The MPC Ren is weird in this regard but it is actually designed to perform this way. When you navigate to an empty track, it will use the settings of the last track you were on.

So if the last track was a MIDI track, going to an EMPTY track and it will me assigned to MIDI. If you have Program 'Bad Ass Drums" on a track and then move to an EMPTY track.....''Bad Ass Drums' are ready to record on that track. The only difference is for Plugin tracks that are assigned an actual plugin. If you move to an EMPTY track after a plugin track, the default will be an MPC program. Having plugins automatically assigned would cause serious issues.

This 'feature' is believed to provide a faster workflow when you record methodically from one track to another. If you jump around (skipping tracks), that it can look confusing.

im i the only person with these errors?


Im on a Mac. Before I copy a sequence, I save everything, because 1 out of every 4 times I do a copy sequence, it crashes.

I just selected a new track, and it crashed. here's the error codes:

Jah,
What do I change in the preferences to keep it from recording before it's suppose to?

Here's a video of the problem. If you notice, during the count in of the record, i hit a pad (clap sound)....when it actually starts recording...the note is there, as if I hit it when it started recording.
