29. to be encountered when tweaking parameters with high feedback e Avoid tweaking too many parameters at the same time and concentrate step by step on subsets usually Starting with Mass Spring force Friction What is this distorted crazy sound I have with high notes As everything is physical in SpringSound it is possible to break the model As it is a software app it won t physically break but may result in unpleasant sound As in real life higher frequency is more likely to break as higher notes strings for a guitar In some special cases if the model is broken you may need to use the Panic button to get everything back to normal behaviour One small trick often working is to raise up Rate and Mass of the Resonator spring have no more sound but had at beginning Physical parameters may result in no sound for example a high Gravity with a low Spring force will result in sticking the weighted body connected to the spring to its lowest position resulting in no sound One other common reason for getting a sound failure is to have a high Static friction and even more Static friction high Mass if the input force is not sufficiently high the weighted body will never start moving The last thing to check is your polyphony parameter if too high for your device this can result in a sound stop Some SpringSound sounds are very nice but hard to play As a real world instrument SpringSound is not always an easy to ply play instrumen
30. ult it is to start moving but the longer it will move due to inertia High mass also usually result in bass sound Spring Define the strength of the spring the higher this strength is the higher frequency you will get The strength can be null in this case nothing calls the spring back to its centre position note that the centre position can be modulated depending on the type of input you select for the spring Spring Linearity Define the linearity of the spring When set to 0 centre position the spring force is linear F k x with k fixed whatever the distance x from centre position is If it is positive the spring force will be lower when distance from the centre position is small If it is negative the spring force will be lower when distance from the centre position is high Friction Define the fluid friction This friction is depending on the speed The higher the friction is the faster the spring will stop moving Note also that the spring will continue moving if the mass is higher for the same friction due to inertia Friction Linearity Linearity of the fluid friction When set to 0 centre position the friction is linear If it is positive the friction will be lower when the speed is small If it is negative the friction will be lower when the speed is high Static Friction Define the static friction This sets a minimum force to be applied before the spring starts moving Note that for high values of this parame
31. ut Its output is fed into the Resonator Spring Resonator spring The Resonator Spring often has a fixed pitch but can alternatively be tuned to the note The connection between the Main spring and the Resonator can be either physical the Resonator steals some energy to the Main spring either theoretical the Main spring doesn t lose any energy in the transfer The output of the Resonator spring directly provides the sound of the Spring Engine Activator The Activator can be seen as a kind of magnetic field applying a force affecting the motion of the Main Spring It can be a waveform square pulse triangle or saw an audio input from the device microphone or from another app a random field or a static value meaning that it will pass through the output of the Pressure Spring who is controlling its level If no activator is selected this also means that the Pressure Spring is ineffective The Activator may be attributed an certain amount of instability lf you are not used to physical modelling but have knowledge of more usual subtractive synthesis keep in mind the following comparison e The Activator and Main Spring are together a kind of sophisticated oscillator VCO e The Resonator Spring can be seen as a special kind of filter or resonance chamber e The Pressure Spring can be seen as a very special kind of ADSR envelope mainly on a VCA e The Impact Spring has no subtractive synthesis counterpart but can be under

33. y This sets the maximum number of note that can be played at the same time If Polyphony is too high for your device this may result in a distorted audio or no audio Here is a set of recommended values e iPhone 4 3 and Buffer Size of 1024 iPhone 4S 5 to 6 and Buffer Size of 512 or 1024 iPad 2 5 to 6 and Buffer Size of 512 or 1024 iPhone 5 and higher whatever you want except if you have 12 fingers on your hand iPad 3 and 4 generation and higher whatever you want Note that additional background application or network mainly GSM activity may result in distorted audio Of course using multiple audio application with Audiobus may also require to reduce the polyphony Buffer Size This sets the internal audio buffer size It can be set to 256 512 1024 or 2048 The lower the buffer size the lower the latency Use higher values if you experience distorted audio CC Chanel This sets the MIDI channel that will be used for the remote MIDI control of knobs The default channel is 11 Copper Balls The copper balls are explained at the beginning of the document You can have 0 1 or 2 active balls The Polyphony has to be greater or equal to the active ball number therefore a polyphony set to 1 requires 0 or 1 active ball not 2 One octave surface iPad only By default the iPad playing surface if two octave wide only one on iPhone Background Audio Select this if you want SpringSound to still be active when in backgroun
