For which platform is SSMN being presently developed ?<\/strong><\/span>
\nMacintosh with Intel processor;\u00a0<\/span>minimal configuration,\u00a0<\/span>MacBook Pro: OS 10.6.6 and up.<\/span>2,5\u00a0GHz Dual-Core Intel Core\u00a0i5 Prozessor (Turbo Boost bis zu 3,1\u00a0GHz) mit 3\u00a0MB L3-Cache\u00a0<\/span>4\u00a0GB<\/span>1600\u00a0MHz DDR3 Arbeitsspeicher.<\/span>and good nerves (-: \u00a0plus lots of patience…<\/span><\/p>\n

What are the basic software components being developed?
\n<\/strong>For notation editing utilizing spatialization symbols : MuseScoreSSMN
\nFor spatialized audio rendering : SSMN_ENGINE_v.1.0. (Johannes Sch\u00fctt)<\/p>\n

What is the role of \u00a0SSMN_ENGINE_v.1.0\u00a0software?
\n<\/strong>This software was developed for the SSMN project in order to allow audio rendering for various composer user cases.\u00a0Here are the more common<\/em> scenarios. The composer may require spatialized audio feedback (listening in surround):
\n1. from an instrumental score (orchestral simulation) containing SSMN symbols and activated (‘played’) from within the notation editor MuseScoreSSMN
\n2. from a live electronics\u00a0environment\u00a0(Csound, MaxMSP, etc.) in conjuction with a score in MuseScoreSSMN
\n3. from audio materials within DAW software (Cubase, DigitalPerformer, Logic) in conjunction with MuseScoreSSMN
\n4. from notation in MuseScoreSSMN\u00a0accompanying visuals (films, slide shows, live video)
\n5. any combination of the above.<\/p>\n

Why are there different versions of MuseScoreSSMN?
\n<\/strong>The original version based on MuseScore ver. 2.0 (in development) was chosen because of its compatibility with Jack and OSC possibilities. We concentrated on implementing 4 symbols : ‘placement’, ‘circle’, ‘line’, and ‘osc’. Today (some 40 versions later), we have implementation for numerous trajectories, several modulation algorithms, and OSC. We also have graphics for performance space, 2D & 3D placements, performers, speakers, microphones, performance objects, and algorithmic connections.<\/p>\n

Why are there different versions of the SSMN-Rendering-Engine?
\n<\/strong>Each version suggests certain possibilities (from basic to more complex) to the user so that he can become more comfortable with this “hack”.<\/p>\n

Why do we need JackPilot for SSMN?
\n<\/strong>JackPilot allows audio \u00a0and MIDI communication between several types of software (MuseScoreSSMN, DAW, AU plugins, MIDI, Rendering Engine, MaxMSP) used in the SSMN paradigm.<\/p>\n

Can MuseScoreSSMN communicate with the SSMN-Rendering-Engine without JackPilot ?
\n<\/strong>Yes, if you wish to observe the spatialization on the Rendering Engine radar as the OSC data transmission is via internal ports and not via JackPilot.<\/p>\n

What do I do if MuseScoreSSMN crashes continuously?
\n<\/strong>Delete<\/span> :
\n– MuseScore Application Support folder
\n(>Users>Library>Application Support>MuseScore)
\n– MuseScore Preferences file
\n(>Users>Library>Preferences>org.musescore.MuseScoreSSMN.plist)
\nNB. In recent OSX versions ‘Library’ is listed in the ‘Go’ scroll-down window when using the ‘alt’ key.
\nReinstall<\/span> :
\nMuseScoreSSMN within the Applications folder.<\/p>\n

How do I configure a quad setup using SSMN software ?<\/b><\/p>\n

Be aware of certain limitations at this time :<\/p>\n

NB1. There is no audio available directly from MuseScoreSSMN MIDI instruments. If you need MIDI to control a synthesizer, we have adapted the Garritan Aria Player to play the MIDI of your MuseScoreSSMN file. Thanks to the Jack Connection Kit (qjackctl) the MIDI from MuseScoreSSMN is directed to the macintosh midi system and automatically routed the Garritan Aria Player in the ssmn-midi-instrument. The audio output of the Garritan Aria Player appears in qjackctl and can be routed either directly to the mac system (no spatialzation) or to the SSMN-RENDERING-ENGINE. In the latter case, the spatialized audio output has to be routed to the system to be heard on your audio setup.<\/p>\n

NB2. Because the needs of composers and their audio setup varies extensively, the SSMN project is currently concentrating on several aspects of rendering possibilities; consequently several versions have been developed to deal with a wide variety of applications.<\/p>\n

1. install multi-channel audio interface
\n<\/i>Skip below to “2. open JackPilot”\u00a0<\/strong>if you wish to continue to Jack<\/strong> right away

Problems
\nIn qjackctl<\/strong>,\u00a0if you don’t see the red connection do ‘stop’ and ‘start’.<\/p>\n

How can we create acceleration of movement using the SSMN symbols ?
\n<\/strong>Only in the initial versions of MuseScore has ‘accel’ and ‘rall’ been implemented. We realize the need for such a feature and will include it in a future release.<\/p>\n

Why can we not use the mouse to design all<\/span> of the graphic symbols instead of having to use numeral input?
\n<\/strong>It is true that several trajectory symbols can be defined with the mouse (line, bezier curve, polygon, polyline, spline). Others such as circle, slinky, lemniscate 8\/\u221e, require numerical inputs for precision, but this question is being reconsidered for a future release.<\/p>\n

Could it be possible to choose values expressed in XYZ, AED, with clear start and end values (not only in degrees) so as to be able to connect symbols easily?
\n<\/strong>This feature will appear in a future release.<\/p>\n

Could the 8\/\u221e figure be modifiable so as to have a larger\/smaller halves)?
\n<\/strong>This idea will be studied and implemented if possible.<\/p>\n
