Welcome Dennis!!

Cheers from Texas!

Try the "hold down arp edit button while powering up" reset trick and see if that helps.

I would like to see Access release a 49 key MIDI Keyboard Controller that looks like the TI2 keyboard, except for of course, it would just be a controller.

Cheers!,

Today as I reach my 48 yrs, im on to an deeper understanding of music, such as a Shamanic/Norse path! a spiritual and healing journey.

Im trying to share my dreams, my visions, insights, healing potential what music are.

That's great to have a spiritual focus! I myself try to share God's love for us through electronic music. The Virus TI2 is the perfect tool for that! Congrats!

One further observation I've made of the wavetables is that the categories that I've come up with (listed above) can be grouped into even larger categories, or rather "types". Keeping these types in mind helps to better understand the basic intent of wavetables and their use as a synth engine sound source. Though naturally they don't identify the categories more specifically, this subjective list of Types may be a helpful starting point for deciding which category might have that table that best suits your tasks at hand. Indeed, the wavetable names themselves sometimes don't allude to their true sonic nature.

I'm not sure this list is actually worth documenting, as a category's type should be self evident once you're generally aware of the different types. It's just a good thing to know regarding this aspect of the original development of wavetables, giving a broad overview of what's been made available for selection.

Six Types, listed with a few examples of Categories:

1. Original Wave Sweep. Category examples: "Analog and Digital Wave Sweep", "Digital Wave Sweep".

2. Synth Function Model. Examples: "Filter Sweep", "Pulse Width Modulation", "Resonance Sweep".

3. Effects Model. Examples: (None on Virus but Blofeld has "Distortion" and "Delay Feedback" FX categories).

4. Musical Instrument Emulation. Examples: "Carillon", "Flute", "Organ", "Piano", "Waterphone".

5. Synthesis Method Emulation. Example: "Phase Modulation".

6. Wave Bank. Example: "Static Waves".

I hope this list can help further your understanding of Wavetables, especially if you are new to this kind of synth method. I certainly wish I had it when I first started! It was all so mysterious to me back then, trying to understand their intent and potential!

Please feel free to add to the discussion if you like. I still have much to learn myself!

Cheers!

Welcome Markus!

Hello stu76 and welcome!,

Osc 1 modulates Osc 2. You can hear the effect in isolation by turning the Osc Balance knob all the way to Osc 2, then adjusting the FM Amount. If you turn Osc Bal all the way to Osc 1 you will not hear any changes with the FM Amount.

Also try the Phase Mod selection in the Osc 2 Wavetable modes. It's a little cleaner sounding and with using sines waves you can replicate very basic (2 Operator) DX tones! And don't forget trying the Waveshaper parameter in the Filter Saturation section, also great for increasing timbre complexity!

Cheers!

I'd like to add that the pins that have been soldered are not the pins that are connected to the MOD wheels pot.

Curious set of circumstances!

I'm not an electronics tech but mentioning if you obtained this TI2 new or used might help.

If it is used perhaps the previous owner tried and failed to fix an existing problem and then just wanted to relieve their-self of the unit? Have you tried the "hold arp edit button" system reset?

If the synth is new I would definitely contact support.

The Unison feature will reduce polyphony if that's what you mean. The only drawback that I know of is that it may also increase volume but you can turn that down with the main volume knob.

Hope that helps!

Yes, very useful! Thank you so much!

Quote from acodmt7

When in demo song mode ? What even is that , never heard of such mode

It's next to the volume knob on the hardware. Personally, I don't think that's a feature that deserves a permanent implementation on the control panel.

Quote from acodmt7

who actually really uses audition buttons ?

It latches and is actually helpful for freeing up a hand when editing parameters that can be accessed by the shift button. Just don't tickle the bug that's there by using the Transpose button at the same time!

See related thread: Shift Button Conundrum

Martin,

Here is a link to a pictorial chart of all the LFO waveshapes, (except #51 for some reason!) useful for getting a visual on how they might perform as a modulation source, though as an audio source in the main oscillator section you would still have to just listen to them, or check my posts for a description chart!

Cheers!

Excellent work, Oli! Maybe we could call your spreadsheet "The Schwalm/atBass Wavetable Description Chart" since it provides a different sorting method.

Thank you Oli for your support for a spreadsheet and thank you to those who responded, or at least viewed my post. I truly hope my research is a benefit to you! Actually, considering the essentiality of the wavetables, I was expecting more interest similar to my Spectral Wave Description Chart but that may be due to the Forum Log-In problem that's been going on lately, as it often still is for me at least.

Now that I'm more familiar with the wavetables, I have revised two of my lists that I presented in old threads:

For my favorite index-keytracked wavetables for creating vocal patches: Opposition, Formantera, Sniper, Decomposer, Morfants, Pingvox, Adenoids, and Element 5.

And for my favorite wavetables for finding a pure basic analog wave at the beginning of a table to use as a carrier wave for the Wavetable PWM mode, or the Phase/Frequency Modulation feature in the Oscillator 2 Wavetable modes: Sine (sine), Sqr Series (square), Didgitalis (sawtooth), and Sinzin (triangle).

As always, your mileage may vary.

Cheers and a very Merry Christmas to all! ,

"glorifying God through electronic music"

Hello all,

Similar to my Spectral Wave Description Chart that was posted in another thread on this forum some time ago, Essay: Spectral Wave Explorations, I am now presenting my Wavetable Categorization Chart for the Virus TI2 here for your perusal.

The Virus TI2’s wavetables are indeed a serendipitous bunch! As you’ve probably noticed by now, they are not numbered, not in alphabetical order, and many have mysterious, enigmatic names. By contrast, dissecting the PPG/Waldorf wavetables was a walk in the park!

With no less than 100 wavetables, the TI offers a huge arsenal of sonic diversity. Complex base ingredients for equally complex sounding patches, sometimes even by using just one wavetable oscillator and only some index modulation, plus some dual Unison or Chorusing to liven things up even more. I have found that most of the wavetables have about four to eight waves posted throughout the table, some of them a dozen or so, and surprisingly, a couple crammed full with about 34 waves, and then one with just two waves!

So, I auditioned each of wavetables in their raw form very carefully in normal wavetable mode and by ear only (no oscilloscope, etc.). Trying different index full-modulation sources, routinely checking individual waves with the interpolation parameter set to coarse, and then subjectively assessing each table’s primary characteristic and real-world usage potential, I then put them into pragmatic categories hopefully making them more manageable for selection as candidates for patch design. To assure consistency, I would routinely recheck my previous auditions as I added more categories. Very tedious and time consuming (but enjoyable and informative!) because of the less wavetables left to audition balanced with the more wavetables left to recheck! Of course, many of the tables could fit into more than one category, but trying to keep things relatively simple, I assigned each table at my discretion to one category only. Auditioning the wavetables in other modes such as Graintable can give different results too, requiring a mode notation if you care to explore things further.

My personal category descriptions are mostly self-evident, but to explain a few- “Carillon” is just a fifty cent word for a group of bells of course; “Chromatic Sweep” here is really any kind of contiguously stepped pitch sweep; “Digital Waves” is any wave that seems like it has more spectra in it than just a normal basic analog wave; “Filter” categories refer to cutoff; “Formant” refers to vocal timbres; “Static Waves” is a table of seemingly unrelated, diverse waves better suited for just single wave selection; and “Wave Sequence” are tables that sound similar to an approximately four-oscillator wave rotation with built-in coarse interpolation.

By necessity, I’ve also included a chart with the wavetable names in their numeric order. An asterisk in either chart denotes that the wavetable has better keyboard coverage, or places middle C where it should be, with an octave shift or two usually downward. (Please note: octave shifting on a keyboard controller does not shift the index of a keytracked wavetable of course, but using the Transpose button on the Virus will have that as a side effect.)

This Wavetable Categorization Chart was put together for my own personal use under my current, somewhat sophomoric level of understanding of synthesis. However, I am confident that you also will find that it does indeed have some merit as presented. You are welcome, of course, to print a copy and adjust the wavetable category assignments to your own preference and to even come up with your own more accurate category descriptions if you like!

Cheers!,

This is a known bug. You can read about it in a thread entitled:

[BUG] TI OS 5.1.3.0 - Freeze while auditioning patch

Same here. I have to log in several times before it takes, if it does at all. You never know which attempt will work and the Stay Logged-In click option doesn't work either. For awhile I started thinking that maybe I'd been black-listed for being too cheerful or something! Support gave me some convoluted work-arounds but I'd rather they just fix this bug! I'm surprised I even got on now.

Quote from charonme

The original cause would still remain in the OS, wouldn't it?

Perhaps. If it is just a program conflict stored in a buffer maybe a reset would clear it. If it is a real OS bug or hardware malfunction it would probably not go away or just show up again later without some other fix that you should contact support about. Then there's always to try installing a new battery option which I'm not sure is user allowed. But yes, always backup your work first, of course.

Quote from charonme

But mostly I'd be interested if someone with a TI/TI2 tried to reproduce it with a positive or negative result

Could not reproduce the problem here. Sorry I could not be of more help!

Does it work normally if you change sustain level before you hold a key down?

I wonder if a factory reset would help you? I found this quote on a 2009 thread of this forum:

"With the Virus TI unplugged, hold down the "Arp Edit" button, located under the "Master Volume" knob, and plugin the Virus TI. You will see two LEDs (BPM and Logo LED) start flashing back and fourth - this indicates it is ok to now let go of the "Arp Edit" button and let the TI boot. All factory parameters * will return to their original settings.

Alternately, if your TI is off via the "Sleep" function (both transpose buttons) - simply hold down the "Arp Edit" button, located under the "Master Volume" knob and the TI will reset.

*note - this does not include factory sounds or banks."

Great work! Thank you!
