FF if no modulation is desired which lets you choose from the various modulation sources mentioned above and modulation amount The modulation amount can be positive or negative With positive amounts an increasing control signal increases the value of the parameter being controlled With negative amounts an increasing control signal decreases the value of the parameter being controlled A setting of 00 is equivalent to tuming off the modulation source Note that having two modulation inputs available allows for interaction between two modulation signals Example If a parameter responds to keyboard velocity and an envelope generator the parameter will follow the general envelope shape but also be influenced by the velocity Ifa baseline setting exists modulation amounts add or subtract values from that setting Example 1 If the filter cutoff is set to a certain frequency positive modulation amounts will increase that frequency and negative modulation amounts will decrease that frequency However modulation cannot force a value beyond its maximum range Example 2 If the filter cutoff is at the lowest possible frequency then maximum positive modulation will vary the filter cutoff from the lowest to the highest frequency Applying negative modulation will not affect the filter frequency because if it s at its lowest value it cannot go any more negative To achieve modulation you must first assign a source This source can be something
