Cakewalk TTS-1 is a GM2 (General MIDI 2) compatible, multi-timbral, multi-output, software synthesizer featuring a newly developed software synthesis engine, with 256 sounds and 9 drum sets built in.
To select a different sound for any of the sixteen parts, click the name of the current sound that's just to the right of the volume fader in the desired part, then select the name of the desired sound from the menu that appears.
In the Mixer window, you can select the sound, set the volume, and adjust the effects for each part. Changes in the various parameters can be made by dragging a knob up or down. You can also click the spin button below a knob to adjust the value of a parameter in terms of its smallest increments.
Note : Some parameters below are labeled GM2 (General MIDI 2). GM2 parameters will change in response to GM2-compatible MIDI messages. The other parameters are unique to TTS-1.
Here's a description of the Mixer Window's buttons and controls:
When you click a part's Edit button in the Mixer window, the Part Edit window appears. The Part Edit window displays the same controls you see in the Mixer window, but adds many more controls for manipulating the sound of an instrument.

Most of the parameters that can be set from the panel of this software can be edited using MIDI control changes and RPN (Registered Parameter Number) or NRPN (Non-Registered Parameter Number) messages.
Here's a list of common problems and solutions:
Sound is too loud/too soft/cannot be heard
Sound is interrupted/playback tempo is irregular/playback stops midway through
Note, however, that if the MIDI data you are attempting to play is of such complexity that it requires sound processing capabilities that are well beyond those of your computer, these measures may not help.
Depending on the performance of your computer, and on the specifications of your host application and audio device, it may not be possible to resolve this problem.
Insufficient polyphony/Notes are omitted
It is possible that this is being limited by the maximum polyphony setting. Check the LIMIT setting for POLYPHONY in the System Setting window. Note: You can check the actual polyphony in the [POLYPHONY] area of the Mixer window.
Effects (reverb/chorus) are not applied to the rhythm part
For the drum part, the effect send amount (send level) is set individually for each drum instrument.
Even if the send level of the drum part is specified from the Mixer window, or from within the music data, there will be no effect if the send level of each instrument is turned down.
Make sure that the music data also specifies the send level of each instrument to which you want to apply the effect.
For details on effect send level settings for drum instruments, refer to See Using the Rhythm Edit Window.

**NRPN**
The NRPN (Non Registered Parameter Number) message allows an extended range of control changes to be used.
To use these messages, you must first use NRPN MSB and NRPN LSB messages to specify the parameter to be controlled, and then use Data Entry messages to specify the value of the specified parameter. Once an NRPN parameter has been specified, all Data Entry messages received on that channel will modify the value of that parameter. To prevent accidents, it is recommended that you set RPN Null (RPN Number = 7FH/7FH) when you have finished setting the value of the desired parameter. Refer to Supplementary material "Examples of actual MIDI messages" <Example 4>. On the TTS-1 devices, Data entry LSB (llH) of NRPN is ignored, so it is no problem to send Data entry MSB (mmH) only (without Data entry LSB)
NRPN messages are used only for TTS-1. Since the VST instruments cannot use exclusive messages, some of the functions defined by General MIDI 2 are assigned to NRPNs to be used with the TTS-1.
On the TTS-1, NRPN can be used to modify the following parameters.
* Parameters marked "relative change" will change relative to the preset value. Depending on the sound or the pitch range, this may have no effect.
* Parameters marked "absolute change" will be set to the absolute value of the parameter, regardless of the preset value.

n = MIDI channel number : 0H-FH (ch.1-ch.16)
mm = upper byte of parameter number specified by RPN
ll = lower byte of parameter number specified by RPN
**RPN**
The RPN (Registered Parameter Number) messages are expanded control changes, and each function of an RPN is described by the MIDI Standard.
To use these messages, you must first use RPN MSB and RPN LSB messages to specify the parameter to be controlled, and then use Data Entry messages to specify the value of the specified parameter. Once an RPN parameter has been specified, all Data Entry messages received on that channel will modify the value of that parameter. To prevent accidents, it is recommended that you set RPN Null (RPN Number = 7FH/7FH) when you have finished setting the value of the desired parameter. Refer to Section "Examples of actual MIDI messages" <Example 4>
On the TTS-1, RPN can be used to modify the following parameters.

<OMNI OFF (Controller number 124)>
n = MIDI channel number : 0H-FH (ch.1-ch.16)
* The same processing will be carried out as when All Notes Off is received.
<OMNI ON (Controller number 125)>
n = MIDI channel number : 0H-FH (ch.1-ch.16)
* OMNI ON is only recognized as "All notes off"; the Mode doesn't change (OMNI OFF remains).

<Decimal and Hexadecimal table>
In MIDI documentation, data values and addresses/sizes of exclusive messages etc. are expressed as hexadecimal values for each 7 bits.
The following table shows how these correspond to decimal numbers.
* Decimal values such as MIDI channel, bank select, and program change are listed as one (1) greater than the values given in the above table.
* A 7-bit byte can express data in the range of 128 steps. For data where greater precision is required, we must use two or more bytes. For example, two hexadecimal numbers aa bbH expressing two 7-bit bytes would indicate a value of aa x 128 + bb.
* In the case of values which have a (+/-) sign, 00H = -64, 40H = +/-0, and 7FH = +63, so that the decimal expression would be 64 less than the value given in the above chart. In the case of two types, 00 00H = -8192, 40 00H = +/-0, and 7F 7FH = +8191. For example if aa bbH were expressed as decimal, this would be aa bbH - 40 00H = aa x 128 + bb - 64 x 128.
* Data marked "nibbled" is expressed in hexadecimal in 4-bit units. A value expressed as a 2-byte nibble 0a 0bH has the value of a x 16 + b.
<Example 1> What is the decimal expression of 5AH ?
From the preceding table, 5AH = 90
<Example 2> What is the decimal expression of the value 12 34H given as hexadecimal for each 7 bits?
From the preceding table, since 12H = 18 and 34H = 52
18 x 128 + 52 = 2356
<Example 3> What is the decimal expression of the nibbled value 0A 03 09 0D ?
From the preceding table, since 0AH = 10, 03H = 3, 09H = 9, 0DH = 13
((10 x 16 + 3) x 16 + 9) x 16 + 13 = 41885
<Example 4> What is the nibbled expression of the decimal value 1258?
16) 1258
16) 78 ... 10
16) 4 ... 14
0 ... 4
Since from the preceding table, 0 = 00H, 4 = 04H, 14 = 0EH, 10 = 0AH, the answer is 00 04 0E 0AH.
<Examples of actual MIDI messages>
<Example 1> 92 3E 5F
9n is the Note-on status, and n is the MIDI channel number. Since 2H = 2, 3EH = 62, and 5FH = 95, this is a Note-on message with MIDI CH = 3, note number 62 (note name is D4), and velocity 95.
<Example 2> CE 49
CnH is the Program Change status, and n is the MIDI channel number. Since EH = 14 and 49H = 73, this is a Program Change message with MIDI CH = 15, program number 74 (Flute).
<Example 3> EA 00 28
EnH is the Pitch Bend Change status, and n is the MIDI channel number. The 2nd byte (00H = 0) is the LSB and the 3rd byte (28H = 40) is the MSB, but Pitch Bend Value is a signed number in which 40 00H (= 64 x 128 + 0 = 8192) is 0, so this Pitch Bend Value is
28 00H - 40 00H = 40 x 128 + 0 - (64 x 128 + 0) = 5120 - 8192 = -3072
If the Pitch Bend Sensitivity is set to 2 semitones, -8192 (00 00H) will cause the pitch to change -200 cents, so in this case -200 x (-3072) / (-8192) = -75 cents of Pitch Bend is being applied to MIDI channel 11.
# <Example 4> B3 64 00 65 00 06 0C 26 00 64 7F 65 7F
BnH is the Control Change status, and n is the MIDI channel number. For Control Changes, the 2nd byte is the control number, and the 3rd byte is the value. In a case in which two or more messages consecutive messages have the same status, MIDI has a provision called "running status" which allows the status byte of the second and following messages to be omitted. Thus, the above messages have the following meaning.
In other words, the above messages specify a value of 0C 00H for RPN parameter number 00 00H on MIDI channel 4, and then set the RPN parameter number to 7F 7FH.
RPN parameter number 00 00H is Pitch Bend Sensitivity, and the MSB of the value indicates semitone units, so a value of 0CH = 12 sets the maximum pitch bend range to +/-12 semitones (1 octave). (The LSB of Pitch Bend Sensitivity is ignored, but the LSB should be transmitted anyway (with a value of 0) so that operation will be correct on any device.)
Once the parameter number has been specified for RPN or NRPN, all Data Entry messages transmitted on that same channel will be valid, so after the desired value has been transmitted, it is a good idea to set the parameter number to 7F 7FH to prevent accidents. This is the reason for the (B3) 64 7F (B3) 65 7F at the end.
It is not desirable for performance data (such as Standard MIDI File data) to contain many events with running status as given in <Example 4>. This is because if playback is halted during the song and then rewound or fast-forwarded, the sequencer may not be able to transmit the correct status, and the sound source will then misinterpret the data. Take care to give each event its own status.
It is also necessary that the RPN or NRPN parameter number setting and the value setting be done in the proper order. On some sequencers, events occurring in the same (or consecutive) clock may be transmitted in an order different than the order in which they were received. For this reason it is a good idea to slightly skew the time of each event (about 1 tick for TPQN = 96, and about 5 ticks for TPQN = 480).
* TPQN: Ticks Per Quarter Note
In MIDI, individual Parts are tuned by sending RPN #1 (Master Fine Tuning) to the appropriate MIDI channel.
In MIDI, an entire device is tuned by either sending RPN #1 to all MIDI channels being used, or by sending a System Exclusive MASTER FINE TUNE.
RPN #1 allows tuning to be specified in steps of approximately 0.012 cents (to be precise, 100/8192 cent).
The values of RPN #1 and System Exclusive MASTER FINE TUNE are added together to determine the actual pitch sounded by each Part.
Frequently used tuning values are given in the following table for your reference. Values are in hexadecimal (decimal in parentheses).
<Example> Set the tuning of MIDI channel 3 to A4 = 442.0 Hz
Send RPN#1 to MIDI channel 3. From the above table, the value is 45 03H.
