ttm012(Synth D)
The ttm012 is a digital synthesizer with a unique waveform synthesis engine and modulation mechanism. The waveform generation engine is the same as that of ttm002, but it has added filter functions and other features to provide more flexibility in sound creation. Although it calls itself a digital synthesizer, the feel is the same as that of an analog synthesizer, and of course it excels at analog synthesizer sounds as well.
By selecting any one of five different waveform generation patterns and adjusting up to eight parameters, the main oscillator waveform can be generated with simple operation. In addition, modulation and LFO waveforms can be superimposed as sub-waveforms for more complex sound creation.
For final tone adjustment, a high-pass filter, low-pass filter, chorus, and echo are provided.

Parameter Description
Main oscillator waveform type
By clicking the button, you can select the waveform type from Sin/Rect/Rect2/Sin-N/Sin-X. The effect of Param.1 to Param.7 differs depending on the waveform type. Unused Param. will be grayed out.
Sin: Sine waveform can be deformed using Param.1 and Param.2 as the basic waveform.
Rect: Rectangular waveforms can be deformed using Param.1 to Param.7 as the basic waveform.
Rect2: Rect waveform can be deformed using Param.1 to Param.7 as the basic waveform.
Sin-N: Using the sine wave as the basic waveform, Param.1 to Param.3 can be used to deform the waveform. Noise waveforms can be generated by superimposing sine waves multiple times.
Sin-X: Using the sine wave as the basic waveform, Param.1 and Param.2 can be used to deform the waveform. A metallic tone can be obtained by increasing the sampling frequency.
Winodw
Adjusts the range over which the ends of the main oscillator waveform are rounded. The larger the number, the softer the tone tends to be. The image below shows the upper waveform at 0% and the lower waveform at 100%.
Sub-oscillator
Adjust the sub-oscillator.
Mix: Adjusts the percentage of the sub-oscillator volume to be added. Turning the knob to the left adds the LFO waveform, turning it to the right adds the modulation waveform, and setting it to 0 adds the main oscillator waveform at a fixed ratio of 50%. This can be controlled in real time with control change number 20.
Tune: Tune: Adjusts the pitch of the sub-oscillator in the range from -100 (one octave down) to 100 (one octave up). This can be controlled in real time with control change No. 21.
Modulation
Adjust the modulation.
Level: The higher the value, the greater the modulation effect. This can be controlled in real time with control change No. 22.
Time: Adjusts the number of modulations per waveform.
X: Adjusts the modulation waveform.
LFO
Adjust the LFO.
Type: Clicking the button allows you to select the waveform type from Sin/Tri/Saw/Square/Main/Mod." Main" is the main oscillator waveform and "Mod." is the modulation waveform.
Freq.: Adjusts the frequency of the LFO. Freq.: Adjusts the frequency of the LFO, which can be controlled in real time with Control Change No. 23.
Amp.: Adjusts the amplitude of the volume. It can be controlled in real time with control change No. 24.
Pitch: Adjusts the amplitude of pitch. It can be controlled in real time with control change No. 25.
Filter: Adjusts the amplitude of the filter. This can be controlled in real time with control change No. 26.
Filter
Adjust the filter.
HPF: Adjusts the cutoff frequency of the high-pass filter.
LPF: Adjusts the cutoff frequency of the low pass filter.
Reso.: Adjusts the resonance of the low pass filter.
Chorus
Adjust the chorus.
Freq.：Adjusts the frequency of the chorus.
Depth：Adjusts the amplitude of the chorus (the amount of shaking).
Echo
Adjust the echo.
Level: Adjusts the volume of the echo.
Time: Adjusts the echo duration.
Envelope Selection
Select the envelope to be adjusted. Click to select the envelope to be adjusted.
Amp.: Adjusts the volume envelope.
Pitch: Adjusts the pitch envelope.
Filter: Adjusts the low pass filter envelope.
Envelope adjustment by pitch
Envelope adjustment by pitch
Envelope adjustment by velocity
Adjusts the degree to which velocity changes the envelope velocity. The higher the velocity with a positive value, the lower the envelope speed becomes, and the faster the velocity with a negative value.
Oversampling
By clicking the button, you can select how many times the sampling frequency of the internal processing should be increased relative to the sampling frequency set by the host from 1x (x1) and 2x (x2). Increasing the sampling frequency of the internal processing may improve the sound quality.
Envelope level
Adjusts the envelope level. Adjust the volume and filter in the range of 0 to 100, and the pitch in the range of -100 to +100. The envelope level value being adjusted is indicated on the label at the bottom.
A: Adjusts the level immediately after the sound is pronounced.
H: Adjusts the level after the attack time has elapsed.
D: Adjusts the level after the decay time.
S: Adjusts the level after the sustain time.
E: Adjusts the level after the release time.
Envelope time
Adjusts the envelope time. The envelope level value [ms] being adjusted is displayed on the label at the bottom.
A: Adjusts the time to reach level H.
H: Adjusts the time to maintain level H.
D: Adjusts the time to reach level D.
S: Adjusts the time to reach level S.
E: Adjusts the time until level E is reached.
Main Oscillator Waveform
Displays the main oscillator waveform.
Patch name
Change the patch name. Click on the text box to switch to input mode.
Volume gain
Adjusts the volume. The higher the value, the louder the volume.
Save/Load Patches
Saves/loads/temporary saves patch data.
Save: Saves the patch data.
Load: Loads the patch data.
Keep: Temporarily saves the currently selected patch data to preset No. 0.
Tips
Fine-tune the settings.
If you operate the GUI while holding down the Shift key, the amount of change in value is reduced to 1/5 of the normal value, making fine adjustments easier.
