Technical questions for the MPC2000xl and the MPC2000

Figured it out so that I can have a partition of the SD card for the MPC2K (SCSI ID 1) & Triton (SCSI ID 2) with an additional extra partition (SCSI ID 3). SCSI ID 0 is reserved for the GUID Partition Table so that all of the SD card can be seen on OSX.

Figure out what the disk id of the SD card is in Terminal:

diskutil list

Output:

/dev/disk4 (external, physical):
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *7.9 GB disk4
1: EFI EFI 209.7 MB disk4s1
2: Microsoft Basic Data MPC-2000 898.6 MB disk4s6
3: Microsoft Basic Data TRITON 4.0 GB disk4s5
4: Apple_HFS EXTRA 2.6 GB disk4s4

in my case it's disk4. the # value corresponds to which GPT partition it is in the sector starts and sizes section.

Format the SD Card as GUID Partition Table.

sudo diskutil eraseDisk FAT32 SDCARD GPTFormat /dev/disk4

Partition the SD card in Disk Utility:

900MB (the max for MPC2K) as MPC-2000 (MS DOS FAT)
4GB (the max for Triton) as TRITON (MS DOS FAT)
Remainder as EXTRA (Mac OS Journaled)

Read the sector starts and sizes of the partitions in Terminal:

sudo gpt -r show disk4

Output:

SCSI2SD UTILITY SETTINGS:

Maintaining the first sector to the EFI on the SD so that the Partition scheme remains the same means setting SCSI ID 0 start sector to 0 and the sector count to 409640.

the 2nd GPT part (MPC-2000) represents SCSI ID 1, and starts at 411648 and has a sector count of 1755136.

the 3rd GPT part (TRITON) represents SCSI ID 2, and starts at 2168832 with a sector count of 7811072.

the 4th GPT part (EXTRA) represents SCSI ID 3, and starts at 10242608 with a sector count of 5019048.

I put these all into the SCSI2SD utility, every ID's device type is set as Removable.

Flash the settings to the SCSI2SD card, then plug it into the MPC2K, plug in the SD card and the power, turn on the MPC and load up the SCSI ID 1 on the Format section in the MPC. Format it as just one (A) partition, making sure not to format SCSI ID 0 or the other ones. Copy the Operating system from the floppy to SCSI ID 1 Partition A, and take that back to the computer. Load the OS 1.72 and all my MPC programs / files and sounds and everything works beautifully.

I think in this manner you can use one SD card to hold files for multiple samplers. not at the same time but possibly with that bigger box that they're selling in places. will try this out with the Triton soon as I haven't hooked it up to the back of that yet but works great for the MPC and having access to the rest of the SD card.

Ok first problems arise.... i can only put 150 files or less on the root of the 1GB SD partition on OSX. If i put samples in folders in the same partition, it lets me put more files. but right now it seems i can only access a limited number of files on the root. Gonna try see if i can up it by saving more samples in from mpc2k instead of OSX. How do you guys organize your files on the mpcstuff sd card setups ?

only 133 files, 79,3 mb. OSX says disk is full but shows 800+mb free.

OK last update on this, bc that Pretty ricky dude loves to be an asshat on these here forums. Big ups Lampdog being the only user dishing out good info on here, i learn a lot from ya

---------------------------------

This is info for everyone buying the SCSI2SD, that doesnt want to pay Chicken Systems or MPC-stuff for something that should be free.

Here's how to use SCSI ID's 0, 1, 2 & 3 on the MPC2000 via MAC OSX, with the SCSI2SD 5.5.

1. Figure out what the disk id of the SD card is in Terminal:

diskutil list

ex)

/dev/disk4 (external, physical):
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *7.9 GB disk2


2. Format the SD Card as GUID Partition Table.

sudo diskutil eraseDisk FAT32 SDCARD GPTFormat /dev/disk2


3. Make 5 partitions on the SD card in Disk Utility:

900MB (the max for MPC2K) as MPC-2000 (MS DOS FAT)
900MB as MPC-2001 (MS DOS FAT)
900MB as MPC-2002 (MS DOS FAT)
900MB as MPC-2003 (MS DOS FAT)
Remainder as EXTRA (Mac OS Journaled)

4. Read the sector starts and sizes of the partitions in Terminal:

sudo gpt -r show disk2

Output:

start size index contents
0 1 PMBR
1 1 Pri GPT header
2 32 Pri GPT table
34 6
40 409600 1 GPT part - C12A7328-F81F-11D2-BA4B-00A0C93EC93B
409640 2008
411648 1755136 2 GPT part - EBD0A0A2-B9E5-4433-87C0-68B6B72699C7
2166784 2048
2168832 1755136 3 GPT part - EBD0A0A2-B9E5-4433-87C0-68B6B72699C7
3923968 2048
3926016 1755136 4 GPT part - EBD0A0A2-B9E5-4433-87C0-68B6B72699C7
5681152 2048
5683200 1757184 5 GPT part - EBD0A0A2-B9E5-4433-87C0-68B6B72699C7
7440384 488
7440872 7820784 6 GPT part - 48465300-0000-11AA-AA11-00306543ECAC
15261656 262151
15523807 32 Sec GPT table
15523839 1 Sec GPT header

5. Input the values into the SCSI2SD Util:

You leave sectors 40 to 409600 alone because they hold the partition info for the rest of the SD card.

Put these all into the SCSI2SD utility, every ID's device type is set as Removable.

Flash the settings to the SCSI2SD card, then plug it into the MPC2K, put your floppy in the MPC, plug in the SD card to the SCSI2SD and the power cable, turn on the MPC, and then format SCSI ID's 0, 1, 2 & 3. Then take the SD card back to the computer, rename the partitions so that it's easier for you, put OS 1.72 on the first partition and then put all your MPC programs / files on the rest of the partitions.

Delete hidden files on OSX by pressing Shift + command + . (period), every time you put the SD in the computer. Back up your files regularly.
