The battery that supports the back-up circuishould be replaced every five years. Call Roland for battery replacement.(The first replacement may be required before five years, depending on how much time had passed before you purchased the unit.) When the unit is in for service, data in the memory may be erased during the repair work. 5 Connections ГП Connections Sequencer Other MIDI Sound Module (MC-500 Optional) < Ouput Level Switch > H M L ПШ O Keyboard Amplifier M/'H O Recording Equipment H O Mixer L/M/H O Guitar Amplifier L/M An exact copy of the signal fed into MIDI IN will be sent through MIDI THRU. *The signal fed into MIDI IN is not sent from MIDI OUT. 6 OUTLINE OF THE P-330 2 OUTLINE OF THE P-330 The P-330 is a MIDI Sound Module that features various functions. The following explains the features and operational structure of the P-330. 1. FEATURES of the P-330 • SA Sound System The P-330 utilizes SA/S technology to reproduce the timbres, dynamics, and characteristics of many acoustic musical instruments, such as pianos. • Multi Effects The P-330 includes programmable Multi Effects, grouped in Chorus, Tremolo and Equalizer sections. • Patches As you change Patches during live performance, the effects will also be changed as well as the Tone (timbre). In other words, a Patch consists of a Tone and Effects. The P-330 can store up to 64 different Patches. • Performance Controlling Functions MIDI Control messages sent from an external device can change the performance controlling functions on the P-330. • Stacking Function The P-330's Stacking function allows you to set-up more than one P-330, increasing the number of voices to be played simultaneously. 7 OUTLINE OF THE P-330 2. Basic Structure of the P —330 [Tone] The P —330 provides 8 basic preprogrammed Tones. Tone Number of Voices Piano 1 16 Piano 2 16 Piano 3 16 Harpsichord 10 Clavi 10 Vibraphone 16 E. Piano 1 16 E. Piano 2 10 [Patch] A Patch consists of one of the 8 Tones and an effect program of Chorus. Tremolo and Equalizer sections. 8 OUTLINE OF THE P-330 [Multi Effects] • Chorus Two types of LFO’s (Low Frequency Oscillators) are provided for the chorus effect. By combining these two LFO’s, various chorus effects can be created. • Tremolo Tremolo is a periodical alteration of the volume of a tone, creating effects similar to vibrato. • Equalizer An equalizer corrects the frequency characteristic of a tone. That is , the brightness of a tone will be altered. 9 OUTLINE OF THE P-330 3. The P —330’s Four Modes One of the following four modes should be selected depending what you wish to achieve with the P—330. [Play Mode] This is the normal playing mode, which allows you to call a Patch you like and play it. [Edit Mode] This mode allows you to edit the parameters and functions of the P-330. #MIDI Functions include MIDI Channels, OMNI mode setting etc. ♦Performance Controlling Functions determine how each function of the P—330 should be controlled by an external device. #Patch Parameters include parameters related to the Tones, such as Sound Selection and Effect settings. *The edited version of the MIDI functions and Performance Controlling functions are automatically written in the internal memory except for a few, while Patch Parameters requires an appropriate writing procedure. [Write Mode] This mode allows you to write an edited Patch in to the internal memory. [Data Transfer Mode] In this mode, Sound data written in the internal memory of the P —330 can be transferred to another P-330, a sequencer or a computer, etc. 10 Basic Procedure [S} Basic Procedure 1. Power—up Make sure that the P—330 is properly connected to the external dcviccs, then lake the following procedure. Step 1 Turn the P —330 on.

Step 3 Turn the amplifier on, then turn up the volume. 11 Basic Procedure 2. Contrast Control of the Display Adjust the contrast of the Display so that the Display can be seen clearly. Step 1 Push the TUNE button. TUNE Step 2 Push the FUNCTION A button twice. LCD Contr.astil- 9 Step 3 Using the FUNCTION TA buttons, adjust the contrast.(1 to 16 are possible.) Step 4 Push the TUNE button. 12 Basic Procedure 3. MIDI Setting il is essential to set the MIDI channcl of the conncclcd MIDI devices to the same number, Otherwise , MIDI messages cannot be communicated properly, and therefore the P-330 cannot be played correctly. If you wish to use the P-330 regardless of the MIDI channel scl on the external device, change the OMNI mode to ON. a.
