68283BV1.MID
By Robbie Rhodes

Attached to this text message is a BinHex4-encoded file containing 68283BV1.ZIP, which (when un-zipped) is 68283BV1.MID.

This is the Ampico roll of Paderewski Minuet, Op. 14, No. 1, played by Sergei Rachmaninoff. Wayne Stahnke transmitted the source file, 68283BAR.MID in Digest 960311, encoded using base64. After I decoded from base64 format I named the resulting file "68283BAR.MID". This file meets the minimum requirements of the Standard Midi File Specification. Because I use a Macintosh computer, it was also necessary to set Type=Midi. I used an old utility named "DeskZap"; ResEdit could also be used.

Then I processed the new Midi file:

1. I added these Meta events at the beginning of the file, which contain data for Meter and Tempo, so that the file will play at 800 ticks per second:

(in header)   Ticks per qtr_note = 240
FF 58 04 4/4 Time, 24 tix/beat, 2 32nds/24tix
FF 51 03 rMM 200.0 300000 usec/qtr_note
FF 54 05 SMPTE Offset: 64 0 0 0 0 ;required by some editors

2. I created new Loud Pedal (#64) and Soft Pedal (#67) controls from the "tracker bar notes", Ampico 3B and 3T, respectively.

3. I created new Midi-Velocity values with my program called "Ampico-A Player". I don't want to call it an "Emulator" program, because it is not tested. In particular, my modeling of the A amplifier and crescendo is very simplified.

The final version sounds quite nice on my Roland piano synth. My editor, MasterTracks Pro (Macintosh) displays the Midi velocities, and shows the crescendo actions.

For Horst and Wayne (because you both have written "emulators"):

A fast and simple way to exhibit the expression in the file is to create a histogram, which shows how many times each discrete velocity was used. The table of values (below) shows that the quietest intensity was MidiVel = 37; this is the "Cancel" mode. The action of the Crescendo and Amplifier adds extra MidiVel, et cetera.
