Yamaha TX81z

Some pics of this Yamaha Tone Generator.


Though its only 4 operators , it sounds great.


Maybe a new classic??
It can be configured to act as 8 independent instruments.  .... each controlled on a different midi channel.

It's a 1-unit rackmount module ...basically a key-less version of the DX-11.
The sounds are similar to the DX-21 and DX-27. 

 The TX81Z has 5 banks of 32 voices. Banks A-D contain factory preset voices.
Use the PARAMETER keys to select banks I, A, B, C, D. Use the DATA ENTRY keys to select voices 1-32 in each bank.

 




...jUST 8 algorithms 




 A pull-out card lists the main operations of the TX81Z.
 --------------------------------------

You can edit your own voices... In single mode , press the edit-compare button.


 Use the PARAMETER keys to move through the parameters, Use the DATA ENTRY keys to change the datavalue. When the LCD shows several parameters at once, use the CURSOR keys to move the blinking cursor to the parameter you want to set.

While editing a voice, you can compare it with the original voice. Press EDIT/COMPARE. The LED will begin blinking, and the LCD will show a “c” in theupper left corner, indicating “Compare”.Use the PARAMETER keys to lookthrough the parameters.

Wasp filter Vintage and AE modular

I'm just getting into the AE modular.
The lovely small format is esp useful for live performance.
I can carry a whole modular in a small suitcase.
And its battery powered.

A friend asked me to do a video comparing WASP filters.
I hope this helps the community.


The Tangible Waves / Abused Electronics modular
https://www.tangiblewaves.com/


The WASP filter is based around a simple CMOS chip.
The 4069.... its an inverter.
If you're going to build one the CMOS ic has to be unbuffered  ... use CD4069UB
The original vintage circuit also uses the CA3080 ... a OTA...Operational Transconductance Amplifier

The AE modular wasp inspired filter uses vactrols for controlling the filter frequency.​

Jasper-Wasp build pics


Jasper Build notes. I'm building this for a friend.
These aren't official notes and I'm not a professional Synth Technician..
Just my personal thoughts to help me trouble shoot if I encounter any probs.

The official website where you can buy a kit is here:
jaspersynth.co.uk

There are lots and lots of CMOS ICs. This is almost a Lunetta synth. Here is my page on CMOS &  Lunetta synths


Anyway, the integrated circuits used in this build are mostly CMOS (with a smattering of the occasional op-amp). I've got a few old vintage WASPs and I love how they sound .esp considering the simple components.
This is the main Jasper PCB. The keyboard is attached.
I like how the colour of the keys is reversed.

 iT should be a fun build. This is a rev 2.2 , July 2017 PCB.


Here is a list of the ICs used.
LM386 or NJM386D
555
CMOS 555 like TLC555CP recommended
LM3900

CD4006 - shift register
CD4013 - dual flip flop
CD4016 -- analog bilateral switch
CD4019
CD4024 - shift register
CD4028
CD4040-- counter .. binary,ripple
CD4046 .. PLL phased locked loop... probably the VCO
CD4052 .... multiplexer.. dual 4 channel
CD4069UBE... its an inverter ... I think this is part of the wasp filter ???
CD4070... XOR gate
CD4071....quad two input OR gate
CD4081... quad 2 input AND gate
CD4503
LM13700
CD40103
CD40174

There are many ways to build this but I like to put the IC sockets on first.

Then caps, resistors, etc. All the simple non polarized stuff.


Electro caps are polarized. Insert thus: Long lead in square hole.


The link port cable on the underside of the main board.
 The switched pots.


Fix everything into place then solder.

The rotary switches. You need 6 of these.
These are 2 pole, single level.

two alternatives
LorinCK1060
Alpha SR2612F

I went with the Lorin... more expensive.

 You need to cut the shaft to the right length.


You can set the number of positions with the key washer:
In the pic below, it's set to 4.

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

The original vintage circuit also uses the CA3080 ... a OTA...Operational Transconductance Amplifier instead of your standard Op-amp
An OP-AMP is a Voltage to Voltage amplifier.
The OTA is like a op-amp but the output is a current source instead of a voltage source.
Also the OTA has 3 inputs (unlike a op-amp with 2) . The 3rd input sets the gain with a current.

Yamaha DX5 - 2. Function Mode

The DX5 has the same 3 modes: Play, Function & Edit that you find in the DX7.
It's also colour coded like the DX7.

1. Play (white)
2. Function (green)
3. Edit (violet)

The Function Mode
The colour for the Function Mode is Green.
This concerns the programmable parameters that are not concerned with voice programming.
It concerns the various effects you can apply while playing (like after touch & Modulation wheel settings) as well as things like voice data load/save operations and checking the battery.

To access the Function Mode you need to press this GREEN FUNCTION BUTTON


Below are the Function Job Tables. (you won't see this on a DX7).

tHESE are on the front panel of the DX5 itself.

It shows the various jobs that can be done by using the performance memory / function switches.
(B1 to B8 & P1 to P8)
These switches are dual use (we are using the green function bit)
The Job groups are further divided into 4 sections:
a) Tune (B1)
b) Performance Memory Parameter (B2 to P3)
c) Memory Management (P4 to P7)
d) MIDI (P8)


a) Tune (B1)

Master Tune (B1 - Job1)
Adjusts the overall tuning ...
Both A and B channels are effected simultaneously.
Master Tune data cannot be stored.

-63 to + 63 range.
+0 = A3 is at 440Hz
 -63 = overall pitch of keyboard is 75% lower than standard.
+63 = overall pitch of keyboard is 75% higher than standard.
Use the data entry slider to adjust.

Dual Mode Detune (B1-Job2) 
To get to job 2 just press the B1 button again 
This allows you to detune A & B channels
Creates chorus effects

Range : 0 to 15

0= no detune.


b) Performance Memory Parameter (B2 to P3)

Poly/Mono (B2-Job1)
Controls mono vs poly voice
Use Data Entry -1 for poly , and +1 for mono

In mono mode, acts like a last note priority monophonic keyboard.
In poly mode, The KEY ASSIGN MODE setting is impt.
SINGLE = 32 notes can be played simultaneously.
SPLIT = 16 notes can be played simultaneously on each side of the split point.
DUAL =  16 notes can be played simultaneously.

Source Select (B2-Job2) 
Selects the control source for the two voice generators.
To get to job 2 just press the B2 button again
The control source can be the Keyboard (Normal), a external sequencer, a computer.

Data Range: 0 to 16
0= keyboard
1-16 = corresponding midi channel.
Voice channels A and B can have different Source select settings.

Pitch Bend Range (B3-Job1)
Selects the pitch range of the pitch bend.
range 0 to 12
The pitch bend range will have no effect if Pitch Bend Step is set to a value between 1 & 12.

Pitch Bend Step (B3-Job2)
To get to job 2 just press the B3 button again
Stepped pitch bend effect : Range Between 0 to 12
           0 = smooth pitchbend with no steps.
           1 =  semitone steps
          12 = 1 octave steps.
Voice channels A and B can have different step settings.

Portamento / Glissando (B4-Job1)
Portamento = smooth
Glissando = stepped ... semitone steps.

Portamento Mode (B4-J2)
 To get to job 2 just press the B4 button again
Four modes are available:
1. Retain (Poly mode)
2. Follow (Poly mode)
3. Fingered (mono mode)
4. Fulltime (mono mode)

DX 5 - 3. Edit Mode

The DX5 has the same 3 modes: Play, Function & Edit that you find in the DX7.
It's also colour coded like the DX7.

1. Play (white)
2. Function (green)
3. Edit (violet)

Edit Mode  

Edit Mode is where we edit the voices and can also create new voices.
Notice the colour .. the violet colour indicates its part of the edit mode.

Entering Edit Mode is done here: EDIT/COMPARE
 You can switch between channel A and Channel B voices by pressing the violet EDIT A & EDIT B switch
Individual voice parameters are selected by pressing the appropriate violet labeled switches & programmed using the data entry slider / switches. These are identical to the DX7.


In some instances, you will want to compare the original sound to an edited one.
Do this by pressing the edit/compare switch again.
To save edited voices, you need to enter the store mode


Operator Select

There are six operator select switches. OP1 to OP6 ... just press the one you wish to work on.
Only one operator can be worked on at a time.
The operator on/off switches are below.

Working from left to right these are the next set of switches;


Algorithm.
Permits selection of any of the 32 algorithms.
Use the Data slider / switches.

Feedback Level
Feedback can be applied to one operator in any algorithm.
This controls the level only.  Range : 0 to 7
Use the Data slider.

Operator Output Level.
You can control the output level of a selected operator.
range; 0 to 99
If the operator is a carrier you will effect the volume.
If the operator is a modulator you will effect the harmonic spectrum & timbre.


EG select EG/Pitch EG
This is linked to the Envelope Generator Switches: R1- R4 & L1 - L4
These switches select the EG parameters to be worked on.



Some envelope examples


 MODE
Permits selection of
The Frequency Ratio or Fixed Frequency Oscillator Mode
1. Frequency Ratio -- operator pitch is scaled to the keyboard was you'd expect.
2. Fixed Frequency --- a fixed freq is produced no matter which key is pressed.
                      (frequency is set using the coarse and fine switches - described below)

COARSE, FINE
These parameters determine the actual frequency of each operator.in the Frequency Ratio or Fixed Frequency Oscillator Mode.

For The operators functioning as carriers ... pitch is determined.
For The operators functioning as modulators ... timbre is determined.
ie the harmonic spectrum of the sound.

DETUNE
Permits slight detuning of the selected operator in relation to the others..... to create richer, fuller voice effects.... depends on whether the operator is a carrier or modulator.
Carrier ---- thick multi instrument effect.
Modulator --- results in periodic variation in timbre similar to a phase shift effect.

SCALING
These 5 parameters make it possible to vary the EG level of each operator across the keyboard in many ways.
LD - Left Depth
LC - Left Curve
BP - Break Point
RD - Right Depth
RC - Right Curve


SCALING: RATE SCALING
Shortens overall envelope length as you go up the keyboard ... imitates stringed instruments
Range: 0 to 7

SENSITIVITY : key Velocity
Range: 0 - 7
Applied to a carrier--- produces louder sounds
Applied to a modulator -- effects the timbre

SENSITIVITY :Amplitude Modulation
Sets the sensitivity to LFO AND EG BIAS. applied via any controllers (breath, Foot pedal, mod wheel)
LFO - applied to a carrier - effects tremolo
LFO applied to a modulator ---  periodic variation of timbre.
EG Bias - applied to a carrier --- volume comtrols
EG Bias applied to a modulator --- brilliance control

LFO : Wave
Permits selection of a LFO waveform. There are 6.
Use the data entry control slider or switches.
 LFO : Speed
range : 0 to 99
99 = 50Hz

LFO : delay
You can set a delay of 0 - 3 secs before the LFO starts (after a key is pressed)

LFO : PM depth
Sets the depth of pitch variation.of the LFO.
range 0 to 99

LFO : PM Sensitivity
Sets the sensitivity of operators to PM to LFOs or controllers.
Range: 0 to 7

LFO : AM depth
Sets the depth of AM (tremolo or wow) produced by LFOs  for all operators simultaneously.
This is independent of the various controllers.

LFO : Key Sync
Either on or off
on= modulation begins when key is pressed
off = the LFO is free running and modulation commencement is random.
 
Oscillator key Sync
Normally all oscillators are syncronized.
You can turn this off or on.
When off, oscillations begin at random

Transpose
Permits transposing the overall pitch up or down the keyboard.
Max 2 octaves.

Voice Name
Use this to give voices a name.
Use the OPERATOR SELECT & OPERATOR ON/OFF & BANK /VOICE switches

You will see letters & numbers under each switch.

Dash (-) ,period (.) and space are entered using the Key Assign switches
