Speak and Key Speak by Max for Cats


video upload by max forcats


Speak
Speak is a polyphonic Max for Live instrument that turns typed words into speech in the style of a 1980s Speak & Spell. It encodes each word into coarse chip-style LPC frames and decodes them live in eight voices. MIDI notes set the pitch, so any word can be played as a melody or a chord. It speaks six languages (English, German, French, Italian, Spanish and Japanese), and it can freeze a vowel, stutter at any point in a word and apply a 10-point modulation curve. Vibrato has several shapes and a fade-in, and there are controls for tract size, tilt and intonation.

SpeakKeys
SpeakKeys uses the same voice engine, but each of 48 MIDI keys has its own word and its own pitch instead of speaking one word chromatically. You type a word and a semitone pitch for each key, and a note shows the note that plays it and the note that sounds, so you can program little songs and play them from a keyboard or a clip. The keys are laid out in four banks of 12 and are saved with presets. A pair of mappable Select Key and Select Pitch controls lets you edit all 48 pitches from a few Push encoders. It shares the language, vibrato, global pitch and tone controls with Speak. Max for Cats crafts Software Instruments, Effects, MIDI devices, Sound Design and Samples for Ableton Live.

Olydian VC-01 Vocal Synthesizer - Brooklyn SPEXPO 26


video upload by sonicstate

"Kyle from Olydian Music gave us a look at VC-01 Voicecrafter - a hardware vocal synthesizer with 380 selectable syllables. A touchpad selects syllables, and the keyboard plays them, with MIDI functionality also included. The instrument has two engines: a sample engine based on recordings of sung syllables, and a synthesis engine that uses wavetables and filters to imitate the human voice. The engines can be blended, with reverb and delay available.

The mixer section controls synth/sample balance, consonant/vowel mix, and consonant length. ADSR controls apply to either engine, and glide handles portamento. The sequencer allows entry of notes, live syllable editing, octave and tempo changes, loop point adjustment, and rests.

Engine-specific effects include sample chop, filter, and an autotune crossfade between processed and unprocessed sample versions. Pre-orders are planned soon, with availability next year and pricing expected around $2,000–$2,500.

COMPUTALKER SPEECH SYNTHESIZER



You can find a demo of COMPUTALKER in this previous post from back in 2008.

Here are some pics and additional info on the COMPUTALKER via this reddit thread where you'll find a dropbox link to additional docs including some source code. Note the poster on reddit is looking for help on gettig it going. If you can help, reach out there.

This one was spotted and sent in via
M Me who also found some addtional info here.

From the reddit thread:

"The Computalker CT-1 was one of the earliest commercially available speech synthesizers for personal computers. Introduced in late 1976 and shipped beginning in 1977, it was developed by D. Lloyd Rice and Jim Cooper in Santa Monica, California through their company, Computalker Consultants.

Unlike simpler speech devices that played back recorded sounds, the CT-1 was a 9-parameter formant speech synthesizer. A host computer generated control data describing pitch, formant frequencies, fricatives, aspiration, and other speech characteristics, while the CT-1 generated the actual voice waveform in hardware."

"My goal, (which I do think may end up being completely impossible) is to get this up and running and hear it speak. Among the photos, there are some shots of the inside. I understand that this was originally designed for the S-100 bus going as far back as the Altair 8800. Serial number inside and out is 7001 and I can see that a previous owner likely replaced the older capacitors already.

This variant however, In all my searching I cannot seem to find a single reference to anywhere. My best guess with the information I have is that this could be a prototype version that was meant for later computers and perhaps it's missing some type of interface card for maybe an Apple II or TRS-80?

Here is a dropbox link to all of the information I have collected so far. I have found the manual, the software manual (With source code?!) and all sorts of little information. Also there's a lot more photos....

https://www.dropbox.com...

Maybe someone out there has seen this before? I am super excited to keep collecting information on this! Thank you for checking this out!"

FOC Fibonacci Modulo N Arpeggiator script for Logic Pro


video upload by Ross Totino and Fans of Collision

"The FOC Fibonacci Modulo N Arpeggiator script for Logic Pro creates unique arpeggiation patterns based on the Fibonacci sequence. It maps the sequence onto held notes using a modulo operation, producing mathematically inspired, evolving patterns that are always synced to the host tempo. With customizable settings for step rate, note length, velocity, octave range, and pattern length, this arpeggiator can generate anything from simple, repetitive cycles to complex, layered textures. Designed for both creative exploration and performance, the script is ideal for adding intricate, unpredictable rhythmic and melodic elements to compositions.

GND-1T Speech chip synthesizer Tutorials 4 Keyboard patches & basic editing and expression mapping


video upload by GND-1

"Available directly from https://richardvanhoesel.com/gnd1t

In this installation of my GND-1T tutorials I illustrate how the usual loop based mechanism in this synth can also be used to create patches intended for more conventional melodic expression, such as with a musical keyboard, simply by setting the loop length very short. It also serves as an introduction into parameter editing and expression mapping.

For owners of the 1T, a new bank of factory sounds is available for download on the website. It focuses specifically on 'keyboard patches', in contrast to the more loop & drum factory sounds that the 1T ships with.

As always, everything you hear in these demos is a direct stereo stream recorded from the GND-1T, without any additional processing or effects."

HAL9000 on an emulated IMSAI8080 "War Games" computer, with 80s speech synth


video upload by df9999999999

"I connected a serial port on my IMSAI8080 replica (the computer from the movie "War Games") and wrote a simple BASIC program in XYBASIC to read a text file from disc and output it a character at a time to the SIO Z80 port connected to the physical serial port. The speech synth then speaks the conversation HAL has with Dave Bowman while playing chess, just before he goes off the rails, from the film '2001: A Space Odyssey'.

After each character, I check for an 'XOFF' character, indicating the speech synth's buffer is full and to hold off sending more data. This accounts for the breaks in the text flow on the screen. The synth sends an "XON" character when it is ready to process more text. The program loops waiting for an XON after receiving the XOFF.

To add some visual bling, I also write each character to the Z80 port 0xFF, which is connected to the 8 'Programmed Output' LEDs on the front panel. The LEDs flash with the complement of the ASCII character code when data is sent to the synth."

GND-1T Speech Chip Synthesizer Tutorials 3. Speech Sounds and Circuit Bending Basics


video upload by GND-1

GND-1T instructional demos | All GND-1T posts

"This is #3 in my series of short instructional demos of the GND-1T speech chip synthesizer. This installment provides an introduction to creating speech sounds and applying classic (and new) circuit bends to them. There's a huge number of additional parameters that can be applied to modify the words / loops, including e.g. stereo circuit bends that essentially run twin circuit bending engines. But I wanted to start off more simply.

As always, everything you hear is taken directly from the GND-1T stereo output, without any additional processing or effects. For more information (and to download the user manual), see https://richardvanhoesel.com/gnd1t"

Sampling the Intellivoice Voice Synthesis Module (Intellivision Chiptune) | Simon Hutchinson


video upload by Simon Hutchinson

"By request, I’m posting a free sample pack of recordings from the Intellivoice Voice Synthesis Module, including a simple Kontakt instrument that plays back these files.

Years ago, I made a synth using an arduino and a chip from an Intellivoice. Recently, I went into the closet and dug it out, and, following a couple repairs, recorded some samples for folks that are interested.

Get the sample pack: https://simonhutchinson.com/2023/12/1...

The original Intellivoice Synth Video:"

"Demonstrating a synthesizer built from a chip from an old Intellivoice module (and played back inside the original case), MIDI-controlled through a keyboard or DAW.

Why? Games and gaming hardware are mass-produced devices with planned obsolescence and few serviceable parts. By "hacking" and customizing gaming hardware we regain personal ownership of these devices, and we can turn obsolete equipment into performable, expressive instruments."

1980s Echo text-to-speech synthesizer on the IMSAI 8080


video upload by df9999999999

"I recently was given a 1980s-era Echo PC voice synthesizer box with serial port interface. You simply send text to the both over the serial port and it speaks it. It uses the same chip as the old 1970s Texas Instruments speak and spell.

I figured out how to access TTY2 on the back of my newly completed IMSAI 8080 kit. Using XYBASIC, I wrote a program to speak various well known phrases from misbehaving computers featured in several scifi movies, including War Games, of course.

Accessing the TTY2 serial port on the back of the replica must be done by outputting a byte at a time to port 34. The default TTY2 baud rate was already 9600, matching that of the Echo PC. There is no handshaking. All must be coded manually. The Echo box has a very small character buffer and sends an XOFF command when the buffer fills and a XON when it clears. I check for those conditions in the BASIC program with some simple loops. Hardware handshaking on port 35 could be done, but the flag bit definitions are not well documented.

I set the cadence, pitch and inflection lower than default with a flat inflection that enhances understandability.

I also read the front panel switches to trigger the various phrases."

"Do you want to play a game?"



via Wikipedia
"The IMSAI 8080 was an early microcomputer released in late 1975, based on the Intel 8080 and later 8085 and S-100 bus.[1] It was a clone of its main competitor, the earlier MITS Altair 8800. The IMSAI is largely regarded as the first 'clone' microcomputer. The IMSAI machine ran a highly modified version of the CP/M operating system called IMDOS. It was developed, manufactured and sold by IMS Associates, Inc. (later renamed IMSAI Manufacturing Corp). In total, between 17,000 and 20,000 units were produced from 1975 to 1978."
