Great information thanks, and the service thing sounds reasonable for what it entails.

I understand that a cell can be in a mode to generate 4 waveforms. Does each of the 4 suboscillators have its own fine pitch, phase and amplitude control, and if so are they independently controllable with envelopes? Or is there only one pitch and amplitude envelope control possible for all 4 oscillators together which then stay in fixed relation to each other once configured. I'm kind of asking if the 4 oscillators are prerendered into a table buffer, or if they are generated live. The reason I am asking is that a complete real time phase vocoder/resynthesizer implementation would of course normally require independent control of all 4 subcomponents to count these out as 4 independent timbre partials, otherwise it would be more like 256 cells really only hold 256 partials rather than the potential 1024 suboscillators that have been referenced in the previous hypothetical resynthesis polyphony count.


i think the answer is here:

In fact, the multiple sample is not exactly related to oscillators.
Currently a Cells can controls thru envelope up to 12 samples (this is a software limitations).
The terms oscillators relies to independent envelopes (Amplitude, Frequency, Phase, Waveform). Each oscillator has 2 envelopes for each parameter, one envelope for base envelope and another one for control (eg: MIDI that controls balance between 2 envelopes for a controller assigned to).
Each oscillator has its own wavefomr (Sine, square... programmable short waveform).
The restriction is the Filter parameters; there is one filter function per cell, having its own dual envelope, the filter function applies to all 4 oscillators (or not apply for selected oscillator within the cell).
Also the long programmable waveform (or sample), there is only 2 audible long waveform (>1024 points) per cells, still 12 samples selectable thru envelope with 2 audible on same time.
Also the Links functions (connection from signal to parameters) for a name parameter there is only one possible link in each cell parameter type, or a total of 5 links (Amp, Freq, Phase, Wave, Filter), you choose which oscillator(s) you want to be affected from links.
Also 3 signal inputs to a cell, in this mode a cell is a sampling - processing unit, not Oscillator.
All those operating modes are selected independently for each cell.
Hope this makes things clearer.

Hi,

I take it as you use GOP instead of GFLOP that the processor uses fixed point integers, what size are these.

Also usually high operation counts signify high wattage and therefore high temps.

How are you avoiding this? What is the rating in watts per GOP?

Cheers

I wanna hear some cool fx from an AxcelII.
Is that possible?
Reverbs? Pitch shifters??

Hi Bob
About the Gops and the bit count...
Well there is no simple answer to this as the basic operation is 24 bits, in Synthesis operation the 24 bits processing represent about 25% of all elements. Depending on programs some operations are larger, usually 40 bits, some toher are non symmetrical (16 x 28 for example), in the frequency domain some operators are configured as 40 bits float.

About the operation counts, the main factor to raise the power is the clock, you are right that if you multiply the clock rate, you raise the power factor typically by its square. I experienced it in the 3G cell phones processors. This why some manufacturers would prefer to maintain the clock low and add specialised accelerators and link them to a main processor (or DSP). With the accelerators you put operations in parallel and you save power (other wise the cell phones would keep their charges for an hour instead of 24 hours).

The RPP was benchmarked in concurence with specialised processor with equivalent area rate and 10% less power than accelerators (about 3 watt), less because the RPP is as programmable as standard processor with massive parallelism, with its capabilities the RPP optimize operators use and spread the CMOS switching.

Our RPP is first of its type, Audio is our prefered application as I come from the original Acxel, but the RPP is not limited to it.

Hi Mono-poly
Shortly we will have some of those examples on our website.
Keep in touch.

Hey, this does look great. Examples would be appreciated.

However one thing puts me right off. Having to buy the additional synthesis options. Is this just buying the actually software, or is an extra dsp card needed hence the cost?

With an investment of 3000 bucks, i would want to have access to all the programs the unit could run

The program fully supports the FULL synthesis facilities, as the Acxelink can emulate other Synthesis modes. Also the User can create his own Macros with the Base environment. We include with the base system some prebuilt Macros including SYnths Algorithms, Effects, and Articulations.
We develop different packages as plugins to the main Program that uses the Acxelink but with Visible Parameters in concurent Synthesis Modes. Most of them are developped from third parties.
These elements included or sold separately are not Software but DataBase libraries Sorting different Sound Elements, these are mainly developped by Musicians on a continuous basis.

PostPosted: Thu Jun 11, 2009 7:21 am    Post subject: On the Terms, and what the User get Reply with quote  Mark this post and the followings unread

The idea behind the terms - Acxelink, Macros, Sound Library, Articulation Library is to provide the user different levels of access on Sound:

* Some users prefer experimenting sounds (and like to spend time for it), they will love the Acxelink that opens to an extremely wide sound structure, they are our initial customers, they understand sound structure and want to create sounds, but they are in minority.
* At the other end are the users who compose and play Sequences, produce music etc. they do not focus on creating or experimenting new sound, Many of them do not have Sound Structure expertise, for them we supply prebuilt Sound Libraries and Articulation Libraries.
* In the Middle of the extremes are the User who need to have Sounds to produce their music, to have something ready to use and take some time (and/or interest) to change or personalize their Sounds, to affix their signature - the Sound/Articulation Library and the Macros will allow them to have Sounds ready to use and have the Macros as sound elements. Of course they can also modify existing sounds, the way they want or are comfortable with


To meet the requirements we at Idarca-Audio needed to understand this from the beginnings, we do not want to have the Acxel2 to stay confidential, then we develop different tools and Database (sounds & macros) to make the Acxel2 use to be Democratic and adapted to most.

* ACXELINK (and Additive Synth and Analog Synth modes, included in Package that are higher level representation of the Acxelink) is dedicated for Sound creation, it is the lowest level (native level): Thru Re-synthesis, Acxelink Wide Open Structure, Intuitive User Interface, Macro tools
* MACROS (tool and library): to allow quick access to the Acxel sound creation and use in various modes. Use and modify existing Macros, acquire more specialised Macros (the OpMod options). It is the Intermediate level. Combine whole Sounds from Sound library with Articulation Macros, Sound Macros with Articulations Macros, etc.. Also the Expert can create and/or use macros as base elements of Sounds, in any combination: for example combine Acxelink complex structure with a defined Macro, etc..
* SOUND / ARTICULATION Library: Then the user can work with the Acxel2 without spending a minute to configure it to have it ready to execute composition. He/She has ready to use Sounds and Articulations. Of c ourse it is always possible without limitations to modify the SOunds and the Articulations.

The software and hardware allow the user a complete access on creation. we provide different level of access to meet different users preferences and objectives, on a standard basic we provide the Software, Macro tools, a Macro library and SOuld/Articulation libraries.

The options belong to user having more particular interest: Having Specialised Sound libraryMacro Palette for different Synthesis Modes, Supplementary Multiple Real Time Resynthesis, Supplementary prebuilt Articulation elements.

Hi Teknik
I suppose that you are talking about the Acxel2 Analyzer...
Well the base structure is working fine. We expect updates and upgrades on the analyzer soon next years in particular for multiple Real TIme Analysis (it actually support single signal Real Time Analysis).
About the Acxel2 itself, we are about our schedule and expect RACK-STUDIO deliveries in late November.
Cheers

Hi Pierre,thanks for info!

oh,here in the country between our mates we always talk abouth the 'Acxelizer' since the old one to mean the machine Very Happy

So if one day i would write or talk to someone to tell i just did buy an acxel2 it would probably be something like 'i just did buy the new Acxelizer'. Wink

Well, the sounds certainly aren't of the flamboyant synth demo'ish type. For general instant wow factor, more/other demo sounds would be good. I don't really expect that angle from these guys though. "Knowing what to listen for", I'm satisfied with what I hear, and I know it's capable of a lot more than demonstrated there - good thing too since I have bought one... Laughing
