Book Info

Pages 0, 1, 2, and 3 require a disk formatted on the 01 using the Format Disk command on Page 2.

Page 4 was added with ROM #62. All operations on Page 4 require an MS-DOS formatted disk. This can be formatted using the Format Disk command on Page 4, or on your DOS-compatible PC (format it specifying "720 KB" type formatting).

DO NOT try to remove the disk while the display shows "Now Loading".

This page lets you load an individual Combi, Prog, Song sequence, or sequence pattern from a floppy.

DO NOT try to remove the disk while the display shows "Now Loading".

In all cases, the only option you have is whether to save to File A or File B. A "File" in this case means "All Data", so you can save two different sets of Data (Combi/Prog and Sequences) on one floppy. The easy way to think of this is to remember the 01 uses a 2-sided floppy - side A holds a complete set of data while side B can hold a completely different set.

How to Format a Disk Using Page 2 (for 01 Use Only)

Don't forget to un-protect your floppy - slide the tab so the hole is closed. The rules are:
Write-protect: The hole is open (as in, you can't write on a hole)
Write-enabled: The hole is closed (as if you could write on the tab that closed the hole)

1. Power up your 01.
2. Press DISK to enter Disk Mode.
3. Press "2" to go to Page 2.
4. Press CURSOR DOWN 3 times (or CURSOR UP once) to highlight line 4.
5. Insert a disk in the disk drive.
6. Press "G" or "H" to initiate formatting.
7. You will be asked to confirm that you want to format the disk.
1. To abort formatting, press "G" or "H".
2. To continue formatting, press "E" or "F". The 01 will then display "Now Formatting", and the drive will start making clicking sounds. Formatting proceeds, and will take about 2 minutes (1:56 on my 01).

The terminology on this Page may seem a little confusing. You must first receive and SAVE the data to floppy (the second option on the menu). Later, you LOAD the data from floppy (the first option) and it is automatically sent to the 01 MIDI OUT connector.

As with all 01 floppy operations, do NOT try to remove the disk while the display shows "Now Saving".

DO NOT try to remove the disk while the display shows "Now Loading".

The 01 display will show the number of bytes received. Multiple devices can send data (you might check to make sure they are indicating their MIDI channel in the transmission). There is a 64KByte limit to the total number of bytes received (about 21 seconds worth of uninterrupted data). If you exceed the 64KB limit, an error message will appear and the data will be lost.

When the sending MIDI device is done sending data, press 01 button G or H to save that data onto the floppy in the 01. You will be asked to confirm the save. Confirm by pressing YES (button E). If you don't want to save the data, press NO (button G).

The manual says: "To save a MIDI Data File, the sequence data memory must be at least 35% free."

DO NOT try to remove the disk while the display shows "Now Saving".

MS-DOS format saves a date along with a file name. Here is where you set the date that will be kept with any SMFs you save. This date will be lost when you turn off the power.

Options:

Format 0 or Format 1?
You must select one of these SMF file formats for saving your file.:
Format 0: All channels are merged into a single channel.
Format 1: All 16 channels are kept separated.

I believe Format 0 is an old SMF standard that has no current use. Unless you must be compatible with old MIDI gear, always use Format 1.

Notes:
The file extension ".MID" is automatically added to the end of the Song (file) name.

Patterns are "opened" before being saved to disk. This makes the Song larger than the one with Patterns when it is loaded back into the sequencer. If you were at the limits of Sequencer memory using Patterns, saving the Song to disk and loading it back may push you over the memory limit.

How to Format a Disk Using Page 4 (for SMF Use)

Note: If you bought 720K disks new, they may already be formatted for IBM PCs (MS-DOS). In that case, you don't need to format them again. 1.4M disks must be re-formatted to look like 720K disks.

Don't forget to un-protect your floppy - slide the tab so the hole is closed. The rules are:
Write-protect: The hole is open (as in, you can't write on a hole)
Write-enabled: The hole is closed (as if you could write on the tab that closed the hole)

1. Power up your 01.
2. Press DISK to enter Disk Mode.
3. Press "4" to go to Page 4.
4. Press CURSOR DOWN 3 times (or CURSOR UP once) to highlight line 4.
5. Insert a disk in the disk drive.
6. Press "G" or "H" to start formatting.
7. You will be asked to confirm that you want to format the disk.
1. To abort formatting, press "G" or "H".
2. To continue formatting, press "E" or "F". The 01 will then display "Now Formatting", and the drive will start making clicking sounds. Formatting proceeds and will take 2 minutes.
